Strategy
This will take a raid group, or a very well-geared (ilvl 346+) five-player group as 30 million health will take forever to burn through.

Treat Mobus like a dragon with a standard set of frontal cone and tail swipe abilities. Only the tank should be in front and everyone else should be spread out along one or both sides. Don't clump up, as the Algae area of affect is larger than its model lets on.

Loot
Mobus drops only one piece of loot:

Trivia
His name is an obvious reference to Moby-Dick, the titular whale of the 1851 Herman Melville novel.
