Mahesh, the Bitter
From Destinypedia, the Destiny wiki
Mahesh will spawn after clearing out multiple waves of Taken near a fragmented crystal of the Traveler. It will bombard the player with its Projection Rifle while moving around the condensed area, promoting an aggressive and careful behavior ironically. Killing this boss ends the mission and rewards the player with loot, experience, and Glimmer.
