I fought against an Imp Strangler (ability: Intimidating) with my Zombie Behemoth (ability: Unstoppable). I couldn't attack him :-/ Intimidating description: This champion may not be the target of close-combat attacks, except those made by champions who have Fearless, Unstoppable or Iron Will Please fix this. Thank you and work forward for this great game!
Unstoppable on base doesnt appear to work. If you equip something like a rage band to a unit unstoppable will in fact function normally but the zombie behemoth who has the ability on base can still be stunned and apparently intimidated
