I don’t think it was mentioned here but I do believe it was mentioned somewhere in the forum, also forgot to mention that wind, fire, ice spirits could be added to the weapons to add small buffs. (fire=more damage, wind=faster attack speed, ice=slow foes slightly)
Poison,Vortex,Lightning,Bleeding,Holy,Shadow and so on, yeah, enhancements would definately be nice.
Some really interesting weapons could be made if they were customisable allowing players a sense of freedom without too many weapon models plus the ability to add buffs to their weapons without having to buy a whole new weapon.
