Really? What level is your party? I've beaten him with a level 14
party (which was somewhat tough), anything higher than that should be
no problem (of course the higher the better). Once I've beaten him
with a level 30 party (keep killing enemies on level 21/22 and don't
train new levels), that was so funny... He never had a chance.

Search this forum, you'll find lots of tips on defeating him.
Basically all you'll need is a good a way of bringing him closer
(one/two knights or a thief with lots of sunfruits, casting NEAR FOE,
or a couple of WAND OF ATTRACTIONS for the spell casters). What will
also help: Ensir always casting DISSPELL, so that the Greater Demons
that Kra'an casts can't take away your Shield, and a dwarf casting
Belligerence (double the chance of hitting Kra'an).

You do know that you need the gemstone of balance to complete the
sword, right? You have to hit Kra'an at least once with the incomplete
sword and then visit Helix again.
