GURPS Melee Attack Modifiers

Part of the GURPS For Dummies Cheat Sheet

In GURPS, being successful in hand-to-hand combat involves skill and the right weaponry — melee weapons like daggers, smallswords, sabers, and large knives are effective. When your character is making a melee attack on an opponent during combat, figure your effective skill by

  1. Taking your base skill with the weapon or unarmed attack you are using.

    In some situations, another skill — e.g., Free Fall, Riding, or Environment Suit — will limit this skill.)

  2. Applying the relevant modifiers below.

    Modifiers are cumulative, but combined visibility penalties cannot exceed –10 (–6, if used to blindness). If any modifier marked with an asterisk (*) applies, adjusted skill after all modifiers cannot exceed 9.

A roll of this number, or less, is a hit.
