Headbutt

The character drives their head into an enemy at arm's length. The attack cannot be dodged or parried and deals 1d2 physical damage + 1.5× STR. Roll its critical normally. The technique works only once against each opponent in a combat.

If the blow can reach a vulnerable part of the target's head, it has 1 chance in 4 of leaving the target Stunned for 1d2 ticks. The GM decides whether the target's anatomy, size, armor, and position make this possible.
