Obviously no clerics, since all the weapons are "edgy".
Unless I make some strange dual or multiclass combining cleric and UAI.
But let's see - since they are deathbringers they are not really "good".
They are some sort of evil guys. They kill. A lot.
Hmm, and none of these weapons can be used for backstab. That sucks.
I think Ravager would be very useful in the hands of the Kensai (the flank attacker - right, Xen ?).
Axe of Unyielding could be amplified with a dualwielder with +1 attack offhand weapon - so maybe a Swashbuckler with Belm or Scarlet Ninja-To.
And Silver Sword would be used with the leader - the mighty Fighter/Mage multiclass.
So - F/M, Swashbuckler and Kensai ?
Would they kick ass ?
