sorry to return to some of the complaints at the beginning of the forum, but my archon has a converted hellglaive(decided glaives count as lances, don't know about anyone else) and i normally fight space marines. crap! AP4 after 1st turn is iblith against an army made almost exclusively of models with a 3+ armor.
on the other hand, i could make the argument that a glaive is a power sword, as some glaives are basically swords on sticks.
Death?! You want death?! I'm afraid that would be far too boring.
