RimSteal

RimSteal — Thievery System

"Fortune favors the bold — unless you roll a natural 1."

---

Overview

A fully-featured DND-style thievery system for RimWorld. Right-click any non-allied pawn — human, animal, or mechanoid — select "Steal", and an item selection window appears (the game auto-pauses so you can choose calmly). Then the dice roll, and your fate is sealed.

Core Mechanics

🎲 DND Dice Roll

• Success: 1d20 + Dexterity Proficiency > Item Difficulty + Alertness Bonus
• Dexterity Proficiency = Melee Dodge × 20 + Move Speed × 0.3 (cap 10)
• Item Difficulty = Market Value × 0.03 × Difficulty Multiplier + Mass × Difficulty Multiplier (cap 20, configurable)
• Natural 20 — Critical Success! Automatic success regardless of difficulty
• Natural 1 — Critical Failure! Automatic failure regardless of bonuses

👁️ Stealth Check

• After a successful steal, if faction-aligned witnesses are within 13 tiles, a stealth check triggers
• Difficulty = 10 + number of witnesses (cap 20)
• Uses 1d20 + Dexterity Proficiency
• Hostile factions skip the stealth check entirely — loot them mid-combat with impunity
• Invisible pawns auto-pass stealth checks

🚨 Caught! — Three Choices

• Threaten: 1d20 + (Melee+Social)/2 vs 10. Success: -30 goodwill. Fail: -50, forced return, extra -25 if item already gone
• Deceive: 1d20 + Social vs 15. Success: clean escape. Fail: -50, forced return, extra -25 if item already gone
• Return: Hand it back peacefully — no further consequences

⚠️ Alertness System

• Hidden Hediff on each character, stacks up to 10, decays daily
• Each stack adds +2 difficulty to steal attempts against them
• Failed steal: target gains +5 stacks, nearby pawns +2 stacks
• Failed stealth: witnesses gain +4 stacks
• Repeated theft from the same group gets progressively harder — greed has consequences
