Blood Wall

IroncladSkillCommon
Lose 2 HP.
Gain 16 Block.

You lose 2 HP, then gain 16 Block (20 upgraded). The HP loss comes first and ignores Block, so you cannot pay it with the Block you are about to gain. Dexterity adds to the Block. At 8 Block per Energy it is the most efficient plain Block in the Ironclad pool, at the price of a small, steady HP tax.
