for the top of the tower encounter everyone gets. 725 xp.
Scotty, I think you need to relook at your skill allocation and change those to match your progress to arcane trickster if that is where you are going.
Sorry, things got a little bogged down with these latest encounters the keep has turned out to be harder than even I imagined. but I'm glad i don't have a tpk on my hands. Good work scaling the tower and dropping down the trap door and ladder to waste the baddies.
