In the Lonely Tower, the wizard home level, I bumped into an invisible apprentice, angered it, and subsequently killed it. Can apprentices cast the Disappear spell? Because that would be rather unfortunate.
On an unrelated note; "That was probably a bad idea..." was appended to the ordinary "You murderer!" message. Wizard-testing suggests that this is only given for killing quest friendlies, whereas the quest leader yields "That was a bad idea.". Confirmation?_Train (talk) 17:09, 3 April 2015 (UTC)
