Chaos Elemental

Element Swirl. The elemental has 3 elements at one time (determined by the D.M.). When the elemental takes damage and the damage type is an element that is not currently being used, the elemental takes full damage from the attack, then changes one of its elements (determined by rolling a D6: 1-2 First Element, 3-4 Second Element, 5-6 Last element) to match the damage type. An elemental may not possess duplicate elements (ei. fire, cold, fire is not allowed.)

Chaos Aura. Anything within 5 feet of the elemental will take 1D6 damage for every element type the elemental possesses(ei. 1D6 Fire damage, 1D6 Cold damage, and 1D6 Acid damage)

Zero Mass. The elemental does not take fall damage from falling or being thrown.

Grand Elemental Absorption. If the elemental is hit with an element it currently possesses, heal the elemental for the amount of damage done

Multi-headed. The elemental has advantage on perception checks that deal with sight or sound

Multiattack. The elemental makes 3 separate attacks or 1 combined attack. The Elemental May summon any combination of swords and bows for separate attacks (ei. 2 bows and 1 sword).

Elemental Sword. Melee Weapon Attack: 

 Separate-  The elemental conjures 3 swords, each concurrent to an element it possesses. +9 to hit, reach 10 feet, one target per sword. Hit: 13 (1D12 + 6) (Damage depends on which sword the elemental uses) 

Combined- The elemental combines the swords into a Warhammer. +9 to hit, reach 10 feet, one target. Hit: 52 ((1D12 + 6)(First Element) + (1D12 + 6)(Second Element) + (1D12 + 6)(Third Element) + (1D12 + 6) Force Damage)

Elemental Bow. Ranged Weapon Attack:

Separate- The elemental conjures 3 bows, each concurrent to an element it possesses. +9 to hit, 120/300 feet, one target per bow. Hit: 9 (1D8 + 4) (Damage depends on which bow the elemental uses) 

Combined- The elemental combines the bows into a Ballista. +9 to hit, 240/600 feet, one target. Hit: 36 ((1D8 + 4)(First Element) + (1D8 + 4)(Second Element) + (1D8 + 4)(Third Element) + (1D8 + 4) Piercing Damage)

Attack of Opportunity. When an enemy leaves its attack range, the elemental takes an attack with the weapon it is currently holding (Sword or Warhammer)

Amalgam. When the elemental's hit points reach 0, it will split into 3 separate elementals correlating to the elements the Chaos Elemental possessed when it was alive. See Amalgam Elemental. 

Pressure. When the elemental's hit points reach 0, it will explode. Any creature within 10 feet of the elemental will take 3D10 Force damage and be pushed back 20 feet. There is no save for this effect

Meteoric Burst. Once a day, the elemental may move up to 2x its movement in the blink of an eye (but still noticeable by high passive or active perception) to an unoccupied space. This movement does not impose attacks of opportunity.
