I wasn't talking about 1 turn, but I might have confused them with dendroids. If I did, I apologize; it's been a while since I played Heroes.
What I meant was that 1 turn is enough if you move towards another creature, i.e., the binding takes effect. As for the paralysis of manticores, it lasts for 3 turns, but it doesn't always work... The "luck" percentage is 20%.
