Is Life Barrier stack?

"While you maintain this enchantment, damage dealt to target other ally is reduced by 20...44%. If your Health is below 50% when that ally takes damage, Life Barrier ends."

If Life Barrier stacks, I will play in God mode if I have 3 monks casting this enchantment on me! Any thought?

if you cast an enchantment on someone who has the same enchantment on them already, the old one will be replaced.

the same thing works with hexes, spirits, preparations, and conditions.

like giga said however you can play "god mode" with this spell combined with skills like stoneflesh aura, armor of sanctity, etc and of course high armor...

and stances and dolyak signet

You can stack it with Life Bond. But you can't have 2 copies of Barrier on one character.

Actually, two people can maintain essence bond on the same target. Although I highly doubt Life Barrier can be applied twice, (and even if it could, I doubt the effects would double), there is always an exception to the rule and this might be worth testing.

On a side note, this would not be god mode. Gods can't be stripped of their power by hunchbacks with mohawks.

2 people can reap the rewards of enchanting one person with the same thing, but only one copy of essence bond shows up effecting the target. Life barrier works the same way, but without the beneficial effects. 1st monk puts life barrier on target A then second monk casts life barrier on target A, at this point there is *still* only one copy of Life Barrier on target A and it will be at the effect level from second monk.
Potentially, if there are some similarities with Life barrier and essence bond (untested) if the first monk's health drops below 50% would the enchantment be removed even though the effective copy is from monk 2?

Have you heard of a guy named Abaddon?

I don't see your point.

edit: Oh wait nevermind.
