Sacrificial Will
From Worms Knowledge Base
(Up to Weapons (Worms Unlimited))
This suicide weapon allows the worm to supply power to their comrades which is directly proportional to the worm's leftover health.
Upon usage, the worm's health is instantly turns zero, prompting it to die as usual and ending the turn. However, during the next round the health removed from the sacrificed worm is added to the damage and destructive power (if applicable) of the next attack.
