Seeing how melee weapons are so diverse - 2H sword, axe , hammer, Dual wield knife, sword, axe, shield even... why do magic users have only 1 option - staves?
Why not add say wands, orbs, or something. Weapons that can be 2 handed and others which could be dual-wielded like 1H melee weapons.
Maybe allow a character to use 1 wand and a shield even? They could be a bit shorter range than staff attacks maybe and/or weaker. A lot of possibilities.
This would definitely be something I would like added sometime down the road. Dual wielding wands can make for some fun pew-pew.
