Frennedan

Frennedan is a doppleganger on the second level of Irenicus' Dungeon. He first diguises himself as a innocent old man, who will beg to be freed. If he is refused to be freed, he will take the form of a young boy seeing if you will free him then. If you refuse a second time, or attack him in a human form, he will transform into his normal doppleganger form and attack. If you let him out without harm, he will follow you around a little before trasforming into his normal form and then attacking.
