There is a Taken enemy that looks like a large, black sphere. You encounter them at the Warsat part of the S.A.B.E.R. strike, among other places. You can damage and kill them with several shots.
When you step inside their circles of influence, you get a debuff called 'Shadow Touched.' However, it doesn't seem to do anything to you. The sphere doesn't appear to do anything else either, such as spawn enemies.
Does anybody know the name of this enemy, and what exactly it does?
Thanks!
