As stated in another topic, I propose that the higher your Aggression is, the more effective your strength-based abilities are when under adrenaline.
Overall, Adrenaline would increase your speed and strength.
As for what abilities would be available, we could also have some species-specific abilities, for example:
A flyer may have a "distract" ability.
Shedding its fears for a brief moment, the flyer targets an enemy and increases its own speed dramatically. The targeted enemy pursues the flyer wildly, allowing the others to escape to safety.
It might be possible to level it up so that it affects all enemies within a specified radius, rather than a single target.
Can only be used once per adrenaline state. Counts as "used" only if the targeting successfully hit an enemy (mostly useful if leveled up and the radius clicked has no enemies in it).
