[Suicide Junkie]

"Skips X" damage will turn around and destroy other components when the targetted item is all gone.

"Only X" damage will do nothing if it's target is already dead. Zero damage. This damage type also does not store partial damage, so if the component is too tough to kill in one shot, you can't kill it.

Now, why would a pirate want to destroy the bridge? The SelfDestruct would be a much better choice.
