Drops Schematic: Advanced Magenta Vehemence Crystal. It does NOT drop a white crystal as Ravenite claims. I've got the magenta schem eight times out of ~17 kills. If you can solo it you should -- then no one else will be competing with you for this! I did it as a Level 50 Sentinel with mostly Columi and it was pretty straightforward. It's best to hit your Heroic Moment right before your companion dies, and Unity (if you have it) at the start of the fight.

This boss is easily soloable at 50 and i killed him about 10 times so far, still no signs of the white crystal, his respawn timer is between 2 and 3 hours from what i can tell
EDIT : 25 kills so far, starting to doubt the existence of the white crystal, twice in the last 3 kills he dropped an Advanced Orange Resistance Crystal (+16 endurance)
Starting to think they replaced the white crystal for an orange crystal sometimes after the datamining
