Arcane Mangler

You are adept at infusing the power of the Arcane into large weapons.

Prerequisites: must have the spellcasting feature and be level 8 or higher

• You gain proficiency with Melee Weapons with the 2 Handed Property.
• While wielding Melee weapons with the 2 Handed property 1s and 2s in damage caused by the hit of this weapon may be treated as a 3

• You channel arcane energy into one weapon with the 2 Handed property you’re holding. Using a bonus action you can choose one damage type: acid, cold, fire, lightning, poison, or thunder - for one minute you deal an extra 1d4 damage of the chosen type to any target you hit with the weapon. 
  You can change the damage type, choosing from the options above using a bonus action.

  You can use this ability an amount of time equal to your Spell casting modifier (if multi classing its based on the highest level class you have that gives spell casting) and regain 1d4 uses on a short rest or all uses of it when you finish a long rest.
