Describe the bug
The damage shown after killing an empyrean elite enemy from StarStorm 2 is always shown as 0 and NaN% of the damage. The contributors seem to be tracked correctly, but never the damage dealt.

To Reproduce
Steps to reproduce the behavior:
- Loop until an empyrean elite spawns.
- Kill it.
- Any contributors are shown as having dealt 0 damage as NaN% of it's health.
Expected behavior
The damage numbers should be shown correctly instead of 0 and NaN%.
Additional context
I've only done multiplayer recently, so I don't know if this bug occurs in singleplayer or not.
Empyrean elites aren't spawned as a teleporter boss, or at least I haven't seen one spawned like this. They're spawned as a random event.
