Guild Wars 2

There’s a large number of bosses that die leaving an unlootable corpse. Examples:

Shukov: SE path 2
Mage Crusher: Arah path 3
Giant Terrible Ooze monster (along with every other ooze in this dungeon) Arah path 1
Nightmare Tree: Every TA path
Graveling Breeder: AC path 2
High Priest of Grenth: Arah path 4

I’m sure there are more, but Shukov in particular seems to be an oversight as no one seems to have the JC recipe (or at least no one is selling them) with his name on it and neither of those golems drop bags of wondrous goods.

Just lack of design assigning loottable.
