Ashen's Elemental Form

Uttering an incantation, you draw upon the elemental magic of one of the elemental planes (your choice) to conjure an elemental spirit that takes the form of a glowing translucent armour-like aura that envelopes you. You gain the following benefits until the spell ends:

• You are immune to fire damage (plane of fire), resistance to cold and acid (Plane of Water), Resistance to bludgeoning, piercing and slashing (Plane of Earth), or resistance to lightning and thunder (plane of air).

• You gain a flying speed of 30ft (Plane of air), a burrow speed of 30ft (Plane of earth), or a swimming speed of 30ft (plane of water)

• You have a +2 bonus to AC.

• All your weapon attacks are magical, and when you make a weapon attack, you can use your spell casting ability modifier instead of Strength or Dexterity for the attack and damage rolls. In addition to this, each weapon attack that you deal damage with does an additional 2d4 fire (plane of fire), thunder (Plane of air), cold (plane of water) or bludgeoning (plane of earth)
  
  
• You shed bright light for 20ft, and dim light for a further 20ft (Plane of Fire).
