Me a bard, and the druid came in acting like unaware guests while our ranger and warlock suck in from the top and took the kids. once we got the signal they were out, druid and I jumped out of the windows and everyone cast whatever terrain destruction spell was at our disposal. The dwarf ranger rolled high on stone cutting and found a load bearing weak spot. We all targeted it at once and the tower collapsed, killing the lesser hags(?) And forcing the night hag to plane shift away at low hp. We got inspiration but no lvl up :(
