Special
Once per round as a free action, an operator can take Hit Point damage equal to 3 × the mech’s tier to generate an additional 1 PP. This damage can’t be reduced but can be healed normally. This damage reduces the operator’s Hit Points without affecting stamina.
Necrografts interface with the operator’s body, drawing on their life force to amplify the mech’s abilities.
