Sepulcher of the First Ones - Halondrus Solo (Normal)

Disappointingly easy boss to solo! The orb mechanic can be mostly ignored and in phases 1 and 2 and easily sustained through with low stacks and the tank debuff does not stack infinitely and doesn't hit hard enough at 70 to be a threat. In the final phase the dot from the orbs can stack very high which can deal considerable damage but is easy to sustain through by using a cooldown or two, and there are so many orbs that it isn't worth trying to do the mechanic properly.
