Very interesting playing malphas today.
The video should explain everything. Recommend skip forward a little bit, when I get into the rampage teleporting thing. https://youtu.be/vzT75gUfte8
It has to do with Fireball enchantment.
currently bugged to teleport you all over the place in the Loom into another “instance” - the penultimate rooms.
It also works globally. If you run a Helltide, you’ll find drops and cinders everywhere because you were “part of the kills/dps”. It’s weird.
