Vulnerable

Vulnerable is a debuff that causes the affected target to take 50% more damage from Attacks. It lasts for a number of turns shown by the stack count and decreases by 1 at the start of each turn. Vulnerable stacks can be added on top of existing stacks to extend the duration. The bonus applies multiplicatively with other damage modifiers.

Applying Vulnerable to enemies before dealing damage is one of the most effective ways to amplify burst turns. The Silent and The Watcher have reliable access to Vulnerable application (e.g., Poison Gas, Crippling Cloud, Weave, and various Watcher cards). Enemies can also apply Vulnerable to the player — notably the Blue Slaver and Red Slaver — making it important to plan around receiving it. Artifacts block one instance of Vulnerable.
