Centaur can detect camo like wood elves. They get the inherent rear - which has a 1 tick cooldown, but also the spell rear, which can be cast as often as you have mana.

Rear fails... 20% of the time. Does two moderate damage hits (deva-decimate at low teens) and can occasionally do big damage (MUTILATE) or stun. I'd say the extra bonus lands 1/20.

They also cannot reach the recruiter because of the stupid tunnel!
