Not really, heŽs a mage... he will cast some annoying spells on you. Id recommend completing every candlekeep quest and errands first to get some potions and money. Anyway, there is a weird bug in the game that will make any mage or cleric VERY EASY

- When they are about to cast a spell (i mean they have started casting it and are about to finish the casting), hit pause and they will stop. Just cheesy, but works. you have to be careful with the timing, youŽll get the trick after you practise a bit. But dont use it a lot in the game, it will make it too easy.
