Weak
Debuff
Weakened creatures deal 25% less damage with Attacks.
A weakened creature's Attacks that scale with powers deal 0.75 times their damage; unpowered damage is unaffected.
The stack count is a duration in turns that drops by 1 at the end of the enemies' turn, and a fresh application on a player skips its first tick, so 1 Weak from a monster lasts through your next turn.
Sources include Neutralize, Leg Sweep, Uppercut, Malaise, Red Mask and Weak Potion.

Notes
Paper Krane drops the factor to 0.6 whenever a weakened enemy hits its owner. Debilitate on the attacker doubles the cut, so 0.75 becomes 0.5 and 0.6 becomes 0.2. Weak shrinks Strength and Vigor too, since they are added before the multiplier. Artifact blocks it, and Tracking turns it into a damage multiplier for the Silent.
Rules and timing
- Its duration drops by 1 at the end of the enemies' turn, whoever has it. On a player who did not have it yet, the first drop is skipped.
- It only counts damage from Attack cards and enemy attacks. HP loss and damage dealt by relics, potions and other powers do not count.
