These don't really exist. at the moment, elemental weapons are almost useless, since u can just endow carded or special based items to level or otherwise.
I feel there should be a buff to ranking blacksmith's forged weapons to not only elemental damage but special effects
Flame weapons, which can ignite the soul, or incinerate thy enemies from a forge could burn through enemies' armor/weapons through even a biochemist's fcp. Or increase the attackspeed by igniting the soul of the user aka, using hp/mp per hit to increase the damage or aspd ...
of course thats only an example with artistic flare~
But the lackluster of ranking system for blacksmiths is just a disappointment.
