Oops, I’ve Stolen Something

Last Updated: 180808…,200630

PCs are left occasionally left with time on their hands. Mages & clerics can research spells, fighters can compete in the arena. The thief? Pick Pockets is a simple roll, but what would be the outcome? What if the thief wants to acquire more than a few coppers between adventures? Or the Guild makes a demand that can’t be refused? Theft within an “adventure” context requires one-on-one time with the player and DM, or extended downtime for other players while the thief role-plays the encounter that the DM had to create. Borrowing from various resources, hewing close to 1st Edition rules, I present a system for Pick Pockets and Theft. Rules scattered far and wide are consolidated and streamlined, filling in gaps. Player decisions still affect outcomes. For critical life-or-death moments, tables provide granularity, but the generalities are treated, well, more generally.

Pick Pockets

Up to two pick pockets attempts can be made during a round. A successful Pick Pockets roll gains an item from the victim; the item is determined at random unless the exact location of a particular item is known by the thief.

The potential victim reduces the thief’s chances for success by 5% for every level of experience he or she is above the 3rd, i.e. -5% at 4th level, etc. Chances of success are also affected by the Category of the target: Simple (a lowly farmer), Difficult (a merchant, -10%), or Extraordinary (adventurer/nobility, -15%).

Pick Pockets fails if the player rolls above the chance to Pick Pockets. Undiscovered failures allow additional attempts (twice / round). If the roll fails by 21% or greater, the victim notices the thief’s attempt (the victim might notice and allow the thief to operate anyway in order to track him or her back to the place he or she uses as a headquarters).

Success

Once a pocket is successfully picked, roll 2d10, modified by Category (Simple +0, Difficult +8, Extraordinary +12):

2d10 Result

3 Parchment with a mundane note
4 A key
5 Lower class personal item (rabbit’s foot, needle, dice, playing cards, small knife, etc.) of no value

Pick Pockets Failure

The result of a known failure is adjusted for the Category (Difficult+2, Extraordinary +4).

Burglary

A thief with access to civilization may perform solo burglary missions. Chances of success are identical to the Assassin Spying Table (DMG, p.18).

Theory

Three different “By The Book” foundations exist for determining success of a heist:

  • Assassins’ Table for Assassinations (DMG, p. 75)
  • Assassin Spying Table (DMG, p. 18)
  • The Thief Functions (PHB, p. 28)

The Assassination Table relies on a single roll, and knowing the level of the victim, which could be used to determine reward vs. difficulty. A Spy succeeds based on two rolls (counting Discovery). Using the Thief Functions has a certain appeal, as they adjust based on character level, class, and Dexterity. The Thief Functions can also be modified by magical items (such as Boots of Elvenkind affecting Move Silently). While exercising varied functions would be required for a typical heist, requiring rolls for each individual Thief Function almost guarantees failure. Perhaps an average of those combined values? Pick Pockets would be excluded, given its clear use for a different task. Hear Noise and Read Languages are outliers, leaving Open Locks, Finding Traps, Moving Silently, Hiding in Shadows, and Climbing Walls. That generates an Averaged Thief Function, which lends itself to a rounded/simplified composite of the thief and assassin abilities:

Thief Level Averaged Thief Functions (Rounded) Assassin Spying Table Averaged Composite
Simple Difficult Extraordinary
1 30% 50% 30% 10% 31%
2 35% 55% 35% 15% 35%
3 40% 60% 35% 15% 39%
4 45% 65% 40% 20% 44%
5 50% 70% 45% 25% 49%
6 55% 75% 50% 25% 54%
7 60% 80% 55% 30% 59%
8 65% 85% 60% 35% 64%
9 70% 85% 60% 40% 69%
10 75% 90% 65% 45% 74%

 

The averaged chance of success across all the Thief Functions varies no more than +10% from the Difficult Assassin Spying Table tasks and the Composites, but values are all similar. Using the existing Thief Functions table to determine success hews closer to 1e than directly using the Assassination Table or creating a new composite table.

The more difficult the job, the higher the reward for success but also the higher the penalty for failure? Incorporating the Assassin table, burglaries therefore can be separated into the Simple, Difficult, and Extraordinary.

How long does it take for a successful burglary, when taking into account preparation and execution? Casing the joint is easier and shorter than a spying mission, and the odds of being discovered are less than a spying mission, so the Categories should be adjusted downward from a time and discovery perspective.

Modifiers

What about the invisible PC? A halfling? Wearing Boots of Elvenkind? Using a Chime of Opening? With a high Dexterity? Flying? The composite score combines five different Thief Functions (Open Locks, Finding Traps, Moving Silently, Hiding in Shadows, and Climbing Walls), suggesting a methodology to modify the overall chance of success—adjust the base Thief Functions percentages to modify the overall chance of success. Determine any delta to the individual Thief Function, and adjust the overall chance of success by the delta divided by 5 (to represent the overall change across the five Functions). Using this general methodology, the DM can readily (and less arbitrarily) determine modifications to the chance of success based on player specifics. Two adjustments to the same Thief Function might or might not be considered additive. Any one Thief Function shouldn’t adjusted over 95%. Let’s look at some examples:

  • A halfling is 10% better at Moving Silently, which would increase the overall chance of success by 2% (10%, divided by the five thief functions).
  • If a 5th level thief (Move Silently 40%) were wearing Boots of Elvenkind (95%), his ability to Move Silently is effectively 95%, Move Silently Score could increase by 55%, increasing his overall chance by 11% (55%, divided by the five thief functions).
  • If an 8th level Thief were invisible, his Hide in Shadows ability could increase from 49% to 95% (note the 95% maximum), an increase of 46% improvement in Hide in Shadows, or a 9% increase to his overall chance of success.
  • A Chime of Opening? Open Locks to 95%, but -25% from Move Silently for the time(s) the Chime is used.

PC Characteristics

The effects of Race and Ability score modifiers can be calculated:

Race Heist Modifier
Dwarf +3% +10% Open Locks, +15% Find Traps, -10% Climb Walls
Elf +2% -5% Open Locks, +5% Move Silently, +10% Hide in Shadows,
Gnome +2% +5% Open Locks, +10% Find Traps, +5% Move Silently, +5% Hide in Shadows, -15% Climb Walls
Half-Elf +1% +5% Hide in Shadows
Halfling +4% +5% Open Locks, +5% Find Traps, +10% Move Silently, +15% Hide in Shadows, -15% Climb Walls
Half-Orc +4% +5% Open Locks, +5% Find Traps, +5% Climb Walls

 

Dexterity Score Heist Modifier No dexterity bonuses apply when wearing armor other than simple leather.
16 +1% +5% Open Locks
17 +4% +10% Open Locks, +5% Move Silently, +5% Hide in Shadows
18 +8% +15% Open Locks, +5% Find Traps, +10% Move Silently, +10% Hide in Shadows

 

Armor

A thief wearing no armor gains a +5% Heist Modifier (from the associated +10% Move Silently, +5% Hide in Shadows, +10% Climb Walls, which could affect adjustments from other sources). However, the thief is now at greater risk in any encounters, as they’re no longer wearing armor!

Thieves’ Guild

The thief can increase their chance of success, and make the fencing of stolen goods easier, as a member of the Thieves’ Guild, for a percentage to the Thieves’ Guild. The initiation fee for the Thieves’ Guild costs 1,000 gp (± 500 based on city size, ±500 based on approved theft difficulty). A Thieves’ Guild will require a 15% cut of any crimes committed. Membership in the Thieves’ Guild increases the chance of any success by 5d4%.

There is a 20% chance that the Thieves’ Guild will detect the crime if the thief is not a member.

The Attempt

  1. The thief decides the Heist Category: Simple, Difficult, Extraordinary
  2. Gear up! Calculate the modified Heist Chance of Success (based on stats, magic, race, etc.)
  3. Roll time required to execute the heist
  4. The DM determines the value of the loot, modified by the Heist Category
  5. The DM determines if thief is Discovered (If a thief is discovered, roll on the Theft Failure table)
  6. The PC rolls to determine their Success or Failure
    1. The DM determines the results
  7. The PC decides on the disposition of goods acquired

Chance of Discovery

It takes time to execute a successful heist: making discreet inquiries, identifying a target; casing the joint; waiting for the right moment (moonless night, appropriate distraction, owner out of town); leaving no trace behind. The Base Chance to be Discovered is a cumulative 1% per day spent preparing (subject to a maximum of 10%), minus the level of the thief, to a minimum of 1%. The probability of discovery depends on the Category of the heist:

Heist Category Time to Prepare Probability of Discovery
Simple  1 to 8 days  1%, checked each week
Difficult  3 to 24 days  Base Chance%, checked each week
Extraordinary  5 to 40 days  Base Chance%, checked twice per week

 

Frequency

Repeated heists in a short time will put town citizens on alert! Each successive heist attempted within an identical period (i.e., d8 days from the last Simple heist) will decrease the chance of success by d10%.

Chance of discovery will increase tenfold if a thief is discovered and another heist is attempted during a period of 20 to 50 days thereafter. If the heist is discovered, go to the Heist Failure Table below.

Treasure

The Treasure Category Multiplier matches the crime: Simple (200 gp), Difficult (1,000 gp, +10% to roll), Extraordinary (5,000 gp, +20% to roll)

d100 Treasure Details
1-21 Nothing of Value
22-45 Coins d6 * Category Modifier gp in various coins.1 Note coin weight!

106-119 Roll Twice on this Table Can roll more this result than once, less than this.
120 The Motherload Treasure Type I (gems, jewelry, magic).
  1. Coin distribution varies on Category: Simple (20%sp/30%ep/50%gp), Difficult (30%ep/55%gp/15%pp), Extraordinary (80%gp/20%pp). Multiple % * (value in gp), then adjust for value of coins (i.e. gp value * 20 for # of silver).

Results

Once all modifiers have been tabulated, the DM rolls against the Heist Chance for Success to determine Success or Failure. Success won’t always mean getting away scot-free!

Encounter Reactions

Any intelligent creature conversed with will react in some way to the character that is speaking. Reaction is determined by rolling percentile dice, adjusting the score for the Charisma Reaction Adjustment, and comparing to the table below:

Charisma Reaction Adjustment
13 +5
14 +10
15 +15
16 +25
17 +30
18 +35

 

Adjusted Result (d100) Encounter Reaction
≤01-05 Violently hostile, immediate attack
06-36 Hostile, immediate action
37-64 Neutral – uninterested / uncertain
65-95 Friendly, immediate action
96-00 (or greater) Enthusiastically friendly, immediate acceptance

Disposition of Goods

Turning rare or unusual goods into cash creates its own problem. Anything besides coin requires a fence! Without specific proficiencies, the thief’s appraisal of goods can vary by 10%-200%. Finding a fence will take d4* (1:Simple, 2:Difficult, 3:Extraordinary) days. When first meeting a fence, determine the Fence’s Reaction:

Modifiers (cumulative):

Disposition of Goods Table
d100 Fence Reaction
<01-15 Double-cross (only if value > 5,000 gp). Steals item(s) and escapes (otherwise makes Initial Offer).
16-23 Outraged. Makes Initial Offer but contacts authorities unless member of Thieves’ Guild.
24-29 Fence refuses to deal in commodity. Arrested unless member of Thieves’ Guild.
30-35 Fearful. Fence refuses to deal in commodity.
36-41 Cannot afford goods at this time. Try again in d4 weeks.
42-47 Concerned. Offers reduced by ½.
48-59 Neutral. Makes Initial Offer. Will demand bribe (d6 × 100 gp) for silence if refused.
60-67 Intrigued. Raises maximum offer by (5 × d6)%.
68-83 Neutral. Makes Initial Offer.
84-100 Must Have It. Offers 75% of actual value.

The fence will start with the Initial Offer. The fence will increase the offer by d20% actual value until agreement or the maximum is reached. There is a 10% chance after each offer that the fence will refuse to do business further.

Initial offer: 10% + 5% × d4 of the actual value
Maximum Offer: 15% + 5% × d12 of the actual value

Experience

A thief receives XP equal to 1/10th the value of goods stolen. This is modified by multipliers for the degree of heist difficulty: Simple (× ½), Difficult (× 1), or Extraordinary (× 1½).

Crime and Punishment

A thief arrested will be charged and tried. Fines and jail time are cumulative. Repeat offenders receive stiffer sentences within the Punishment category. The third (and subsequent) conviction always results in the maximum sentence.

Charges

Crime Type  
Trespassing (Simple, Difficult) Class 1
Trespassing (Extraordinary) Class 2

Proficiencies

Below are few examples of relevant proficiencies.

Appraisal

This skill allows the character to make generally accurate (±10%) assessments of common objects, including items made of precious metals and gemstones. The character can also assess, to ±25%, the value of objects of art, tapestries, furniture, weapons, etc., provided a variety of these items are present in the game world. These assessments require no proficiency checks and the DM can roll (d20 or d100) to determine the accuracy of the appraisal.

A character who passes a proficiency check will be able to identify a forgery of a valuable object, to make a very accurate assessment of the value of a common item (within 5%), or to make a general assessment of the worth of an uncommon item, including artifacts. The DM may wish to roll this check, and on a roll of 20 the character makes a wildly inaccurate assessment. Intelligence, 0 Penalty.

Bribery

Successful Bribery includes understanding the appropriate target, the timing of the offer, the amount most likely to generate the desired reaction, whether the one receiving the bribe will keep his side of the bargain, and the best way to avoid drawing attention from witnesses. Bribery allows the thief to judge (75%) how much of a bribe is required. A successful proficiency check (or rolling under half of their Charisma score) will increase one Thief Function by 25%. Failure indicates the bribe is inadequate or refused and makes the chance for success correspondingly more difficult. The character may be reported to the Watch (depending on the Encounter Reaction). Charisma, 0 Penalty.

The cost of a Bribe will vary depending on the Heist: Simple (d10 gp), Difficult (d10 gp × 3), Extraordinary (d10 × 10 gp). More than one Bribe can be attempted.

Disguise

Characters trained in Disguise can conceal their appearance through makeup and costuming. They can make themselves look like any general type of person of about the same height, age, weight, and race. A successful proficiency check indicates that the disguise is successful, while a failed roll means the attempt was too obvious in some way. If the task is more difficult—the character in disguise meets and talks with an acquaintance, for example—an additional proficiency check is required. A successful disguise will prevent follow-up from an Escape or being turned in.

Characters altering their sex, race, or size, must make successful proficiency checks with a -2 penalty for each category. Character may attempt to disguise themselves as a specific person, with a -10 penalty to the proficiency check. These modifiers are cumulative, thus, it is extremely difficult to disguise oneself as a specific person of another race or sex. Charisma, -6 Penalty.

Forgery

This proficiency indicates a skill at creating false documents, mimicking the handwriting of others, and detecting forgeries. To forge a document (military orders, local decrees, etc.) where the handwriting is not specific to a person, the character needs only to have seen a similar document before. To forge a name, an autograph of that person is needed, and a proficiency check with a -2 penalty must be successfully rolled. To forge a longer document written in the hand of some particular person, a large sample of his handwriting is needed, with a -3 penalty to the check.

If the check succeeds, the work will pass examination by all except those intimately familiar with that handwriting or by those with the Forgery proficiency who examine the document carefully. If the check is failed, the forgery is detectable to anyone familiar with the type of document or handwriting—if they examine the document closely. If the die roll is a 20, the forgery is immediately detectable to anyone who normally handles such documents without close examination. It is important to note that the forger always thinks he has been successful; the DM rolls the character’s proficiency check in secret and the forger does not learn of a failure until it is too late. Dexterity, -1 Penalty.

PCs caught after using Forgery on Extraordinary crimes add Forgery to their charges.

Ruse

Ruses are oddities to create distractions, such as hiring mourners to fake a funeral procession outside to benefit his Hide in Shadows Approach, or poisoning the guard dogs’ meat so their reactions are sluggish for the Move Silently check. Like Bribery, the player selects a specific Thief Function to improve. A failed Ruse puts the guards on alert instead, decreasing the Thief Function value by the same amount.

The cost of a Ruse will vary depending on the difficulty of the Heist: Simple (d10 gp), Difficult (d10 × 3 gp), Extraordinary (d10 × 10 gp). Only one Ruse may be attempted per Heist. Intelligence, -2 Penalty.

A DM for *mumble* years, I've been playing AD&D since junior high. I've currently got two separate campaigns running, both in Mystara. I've been told when they handed out hobbies, I stood in the short lines. I actively cycle tour, kayak, play board games, read, develop home automation software, volunteer with the American Red Cross, and work on a never-ending stream of home repairs. In my wake I've left paintball, medieval full-contact combat (SCA), computer gaming, Heroclix, tablet weaving, and kite construction.
