Enchant Element

as the caster speaks an arcane enchantment and does a movement he then shoots a bolt of energy to the target weapon. the caster rolls a d4

1. fire

2. cold

3. thunder

4. acid

by doing this the weapon is given the rolled element causing it to take on the element as its damage type. The wielder of the enchanted weapon does an additional d4 of damage on a successful hit of whichever element the wizard had casted. At higher levels the spell can add different elements at once increasing the d4 by 1 each time per spell level. (EX. level 2 1d4 fire,and 1d4 thunder or 2d4 fire. level three 3d4 of three elements or of 1)
