Traits

Reactionary:  Kaasma Khara gains 3 reactions per round.

Imminent Demise : Failed Death Saving Throws persist, even when regaining consciousness.

Fateful Resilience : After a full round, Kaasma Khara may successfully save on any ongoing effect.

Telegraphed Attacks : Kaasma Khara’s aims for areas when taking turns.  Because of this, you may spend an Action to telegraph the Action turn.

Colossal Size : Kaasma Khara is a massive size beyond category.  Any ranged attacks may target Kaasma Khara, and Kaasma Khara can use Melee or Ranged attack to target anywhere on the battlefield.

Kaasma Crystal : Stitched within the skull cavity of Kaasma Khara is a gemstone of unknown origin - charged with an ancient Astronomical power unable to be deciphered in the heat of battle.  To expose the gemstone, the stitches must be detached by dealing a total of 50 damage using a combination of Slashing, Piercing, or Fire Damage. (Effects that mimic slashing or piercing can be considered, aka, the edge of a shard of glass, etc).  Targeting this spot must be declared, and has an AC of 15.  Dexterity Saving Throws on the spot with this spot automatically fail.

After the gemstone is exposed - the gemstone can be depowered with enough of an electric shock.  If dealt a total of 50 damage from Lightning while the gemstone is exposed, this will weaken Kaasma Khara's overall ability scores - including lowered HP, Damage dealt, and DCs.  Destroying the gemstone adds a stack of Vulnerability to Kaasma Khara.

You may disable one of the following traits/reactions:  Reactionary, Imminent Demise, Immunity Barrier, Psychic Scream.

All Ability Scores drop by 6. Proficiency Bonus drops by 3

Reactions

Immunity Barrier : If Kaasma Khara would take damage from a source, they instead take 0 damage.

Large chunks of meteor begin their path of collision, impacting on each enemy target on the battlefield.  The meteors make their impact at the next Execution Turn the following Round.

Area Turn (20) : Kaasma Khara attacks with Seismic Tantrum.

Move Turn (10) : Kaasma Khara moves across the battlefield.  Everyone underneath must succeed a STR/DEX Saving Throw or be knocked prone, being dealt 3d6 Force Damage.
