nord, 3rd map boss

[ishyrionek]

Should it accumulate (with no expiring time) buff for dmg & def ?
After some time I made to him like 1/3 or 1/4 dmg that i maded when he spawned..
And he keep shining, even after u die, and re-run back to him.
And after some time he killed me ( warrior lol ) with 1 hit.
There were wizzard in game, 1 shot too, and warrior wich number of pves dead increased from 20 to 30, or somethink like that.

Or this accumulate is intended and u have to kill boss asap?

When this boss is at half hp he goes berserk, that is, his dmg, speed and maybe armor and crit chance increase (not sure about the last two).
