Bionics: Steel Skull
This item may never be removed from the fighter it is attached to.
When a fighter with a steel skull would be taken Out of Action in close combat and receives an Out Cold result, they are not taken Out of Action and remain in play. Additionally, this fighter cannot be the target of the Headbutt (Simple) Action. Finally, if this fighter is Engaged and is able to make a Melee attack, they can use the following action:
Headbutt (Simple): Select an Engaged enemy fighter. This fighter rolls a D6 and the chosen enemy fighter rolls a D3, then each fighter adds their modified Toughness to their results. If this fighter's result is higher, the enemy fighter is momentarily staggered and cannot make Reaction attacks the next time they are attacked in close combat this turn. If this fighter's result is lower, their turn ends immediately. In the case of a tie, nothing happens and this fighter's turn resumes.
