Vulnerable
Debuff
Vulnerable creatures take 50% more damage from Attacks.
A creature with this debuff takes 1.5 times damage from Attacks that scale with powers; damage flagged unpowered, such as Wither or non-Attack hits, is unchanged.
The stack count is a duration in turns: it drops by 1 at the end of the enemies' turn and the power leaves at 0.
A fresh application on a player skips the first tick, so 1 Vulnerable from a monster still covers that monster's next attack turn.
Common sources include Bash, Thunderclap, Fear, Bag of Marbles and Vulnerable Potion.

Notes
Paper Phrog raises the multiplier to 1.75 for its owner's hits. Cruelty adds its stack count as percentage points. Debilitate on the target then doubles whatever bonus is there, so 1.5 becomes 2 and 1.75 becomes 2.5. The multiplier stacks with Tracking. Artifact blocks it, and Vicious draws when you apply it.
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.
Changes by version
- Changed Pael's Eye relic: if an enemy has Vulnerable and you take an extra turn, the enemy's Vulnerable no longer decrements before your extra turn (also applies to Frail, Intangible, Weak, and other powers that decrement at the end of the enemy's turn)
- If an enemy has Vulnerable and a player takes an extra turn via Pael's Eye relic, the enemy's Vulnerable amount no longer decrements before the player's extra turn
- Fixed an issue where, if the player dragged a multi-target attack out of their hand, the damage amount previewed on the attack wouldn't include their Strength if some enemies had Vulnerable while others didn't
