Yes, but after that, all the debuff benefits of this skill are lost, because 20 seconds of cooldown makes it usable only once per normal duration combat.
Is it worth it to sacrifice a skill entirely for that?
The only use I found was casting it in the middle of the arena and trapping yourself inside it and letting minions kill the outside mobs. but I stopped using it after 1 Arena run, not really useful for Monoliths
