Incidentally, I don't consider that damage extreme for a level 18 character.

For the curious, assuming mid-level non-limited weapons (avg 16-18... not hard to come by at those ranks, even if gathering them solo would be hard) and maximum strength, I'd estimate the amount of damroll (including the weapons themselves) he's packing from gear to be around 20. Berserk may or not be in play here as well.

A knowledgeable player could gather or purchase that solo at that level.
