[plenty]

Fallowing bsftcs's sugestion, here's a copy of a bug I found during skull castle exploratin:

When u take an item from adriana - u can vanish her (do it quickly!). If she is vanished too close (she continiues to invoke the scroll) or the spell failed - repeat the process (be quic!). If she Vanishes near the entrance (close to the water) she might greet u again and ask for the scroll of banishing. Steal it from her and give it back to her - then repeat the whole process. I managed to get 2x vampire ring and a lich key before she attacked me instead of greeting, and could not be vanished further...
