Possessed by Rage

When you enter combat with no armor at all, and your enemy manages to hit you for the first time (whether it inflicts fatigue, Shaken and/or a wound), rage overflows, your mind snaps and you are possessed by blind fury.
As consequence, you gain the following abilities:

• Just for this first damage, you exit the Shaken state immediately.
• You can perform Savage Attack without becoming Vulnerable as a side-effect.
• You enter into some sort of "battle state" where you move with hellish swiftness, and your opponents hesitate, gaining an equivalent of +2 to dodge.

This has some dangerous side-effects, though:

• You have difficulty telling who's who in the battlefield, after you defeat the opponent that hurt you, you need to roll Perception & Control to decide who's your next target, or you will simply attack the nearest living creature.
• If you need to follow a plan, tactic, strategy or orders, you need to roll Smarts & Control, or continue mindlessly chopping limbs off.

This effect lasts until you are rendered Knockout, Incapacitated, dead, or the battle ends. Whatever happens first.
When you exit your frenzied state, you begin suffering all the penalties at once.

This power is very dangerous when used by people with the Adrenaline Rush mutation.
