I love the cat but also the thumped orc (last one)
My guesses:
Missile defense dodge – shield expertise – better weapon maintenance? – likes to get bloody (morale boost?) – heavy Armour proficiency – Strength -damage and resistance boost? – free cat food? (just kidding love the 9 lives too) – inspires others around him? shield wall leader? – no helmet penalties – light footed… can twinkle their way out of enemy ZoC – can fire a defensive shot when an enemy moves into range? – can switch with fellow BB? – resists all types of freeze effects – can knock an opponent unconscious more effectivelly
