The Devil's Revolver — GM Reference Card v2

Color Key — Base Cost Enhancement Impose Disadvantage Attribute Penalty Follow-Up Delivery Gadget Limitation Power Modifier Limitation

A demon imbued this revolver with evil intent sometime in the 1700s and let it loose to create chaos. It passed through generations of your family, driving each wielder to madness and ruin. The gun draws blood from whoever holds it — forming solid blood bullets with each pull of the trigger. The demon within is fickle and wilful. Displease it, and the gun turns against you.

Affliction 4 — The Curse in the Wound

8 pts

Delivered automatically via Follow-Up when the blood bullet hits and penetrates DR. The target rolls HT-4 to resist — DR gives no bonus to this roll (Follow-Up bypasses it). On failure, all four effects below activate simultaneously and last 1 minute per point the target failed by.

Affliction 4

Target resists at HT-4. Each level imposes -1 to the resistance roll (4 × 10 pts = 40 pts base)

Base Cost

Affliction is the Follow-Up attack. Rides the Innate Attack — no independent attack roll or range needed. Costs +0% because carrier has no relevant modifiers

III

Spirit Reaction — The Demon's Will

Before each use of either ability, the GM makes an unmodified reaction roll (3d). No Talent bonus, no reaction modifiers apply. Repeated attempts within one hour add -1 cumulative to the reaction roll per attempt. Resets after 1 full hour without use.

19+ Excellent	Ability activates normally. +2 to the attack roll.
16–18 Very Good	Ability activates normally. +1 to the attack roll.
10–15 Neutral	Ability activates normally. No modifier.
7–9 Poor	Ability refuses to activate. The trigger is pulled but nothing fires. 1 HP is still paid — the blood was already drawn.
3–6 Very Bad	The gun turns against the wielder. GM decides the effect — the attack may blast the wielder, the curse may afflict the wielder, or something worse. 1 HP is still paid.

Per-Shot Combat Sequence

1	Spirit Reaction Roll — GM rolls 3d unmodified. Apply result from Section III before proceeding.
2	Pay 1 HP — mandatory regardless of outcome. Even a refusal or a backfire costs the blood price. The demon feeds either way.
3	Attack Roll — roll Guns (Pistol) skill ± reaction bonus from Step 1. Target may only Dodge (ranged attack).
4	On Hit — Apply DR — halve the target's DR (Armor Divisor 2). Roll 6d+3 piercing damage and subtract halved DR.
5	Follow-Up Check — if the bullet penetrated DR (dealt any injury), the curse automatically triggers. Target rolls HT-4 to resist. DR gives no bonus to this roll.
6	On Curse Failure — all four effects activate simultaneously: Easy to Kill 5, Vulnerability ×2 Piercing, ST/HT -2, DX -1. Each lasts 1 minute × margin of failure on the HT-4 roll.
7	Corruption — GM records Corruption for the wielder. Track accumulation per GURPS Horror pp. 146-148. This is how the gun drives wielders to madness over time.
