So it's a 90% DR followed by a barrier that's strength is = to the damage you would've taken or is just a 90% DR on ANYTHING that only lasts for a cast, a single swing, a single tick of a bleed? I guess what I'm trying to figure out is say you have an add on you and the boss. You pop it, it triggers from the adds damage or even say you have a bleed that ticks on you. It triggers from that and it's just wasted before the bosses big hit/cast? It gets eaten up by a tick of 10K, you reduced to 1K but the boss all of a sudden hits you for the full amount of whatever it's casting.
