I finally killed the 2 stone golems on the 2nd floor of Rayic Gethra's house, but, when I go to the 3rd floor to kill Rayic Gethra, he stops us & asks why we've interrupted his studies, & to trick him, I say that we're leaving, & then instruct everyone in my party to surround him so we can ambush him by surprise, but, he starts challenging us again. Then he casts fear on everyone in my party except Jaheira, since at the time I've got her casting Doom on him. However, he cloaks himself with some kind of rock armor, that prevents any damage by everyone in my party.

How do I get around this? I've looked to see if anyone posted on this, but, I couldn't find anything in reference to this.
If you can help, I really would appreciate it!!! Thanks in advance!
