I'm going to share with you guys what I did to my game. I played with the following characters:
Dwarf Warrior:
Left Arm:
Spike
Pickaxe
Right Arm:
Scythe
Enric's Sword
Enric (the_hero)
Left Arm:
Shield
Skeleton Shield
Right Arm:
Pickaxe
Kobold Axe
Kobold Spear
All of them are fun to use and the only problems I've ever had while playing as them is that their wrists have the textures of the native character, but the size and shape belong to the old creature the weapon truly belongs to.
