After breaking up the spawns nicely in the spider cave and pretty much out leveling it, I told the group I was heading to pick up spells.
They said they'd be fine as they had 2 healers and a wizard for roots in a pinch.
Imagine my surprise when I was buying said spells and saw all their names go purple, one by one.
I'd like to think they were dragged to and cocooned at the central atmospheric processing unit.
