Enchanter

In my first playthrough, I had Xan in the party (PC Inquisitor Miron Steelsprocket, a LN gnomish cleric ported in from a tabletop DnD campaign I play in) - he was the only wizard we had. His crowning moment of awesome was leaving Candlekeep the second time. He took in a potion of absorbtion, potion of invisibility , and with three charges from a lightning wand managed to slaughter the bounty hunters without him or anyone else coming to a scratch.
