[2019] Nightmare aura?

It's kind of been floated around before, super neat idea. Wondering what other ideas people have!

I would really like more "nightmare" things, being them mods/arcanes/what else, they really make for interesting builds

Or even a corrupted aura, like -enemy armor/-team shield, but this can probably get too close to griefing

If the Corrupted effect was only 'on self' it would be doable!
