I'm a bow nightblade in marksman, hawks eye, no helm.

So I was way up by an enemy outpost where tons of blues were coming out the door to go to battle. My Blessing was about to expire so I decided to pull a kamikaze...cloak and ballista a blue in the face (it helps keep everyone on their toes...a public service, really). Needless to say this aggo'd the 5-8 patio guards and the three blues. I decided to run around and pull lights attacks, rolls, poison inject and cloak to practice evasion.

I ended up with a TON of NPCs and 4-5 blues on me. My health got down to like 15%, then all of a sudden there was a strong red beam on me. My health flew to full like 2-3 times and my guy took off like a rocket. I got like 100 meters away cloaked and then survived. There were no allies nearby.

Any ideas? I've never had that happen before. (And kinda a waste, my Blessing was still about to expire so I still let the blues send me to the gate).
