Immutable Form. This creature is immune to any spell or effect that would alter its form.

Unusual Nature. This creature doesn't require air, food, water, or sleep.

Magic Resistance. This creature has advantage on saving throws against spells and other magical effects.

Shards Within. When hit by an attack within 5ft this creature expels tiny shards of stained glass, dealing 2 piercing damage to the attacker. 

Multiattack. The Creature makes one Shardmouth and one Tendrils of the Broken Void attack.

Shardmouth. Melee Weapon Attack: +9 to hit, reach 5 ft., 1 target. Hit:  (1d10 + 5) piercing damage.

Tendrils of the Broken Void. Ranged Weapon Attack: +9 to hit, range 30/90 ft., up to 5 targets. Hit: (2d6 + 5) piercing damage. When hit by a tendril from this attack, the target must make a DC 12 Strength or Dexterity saving throw (their choice) or be grappled by the creature. While grappled in this way, the target takes 1d4 piercing damage at the start of their turn.

Essence of the Void. As a bonus action, this creature can dissipate its body into the void around it and reconsolidate itself in an unoccupied space it can sense within 30 ft. 

Shield of Shards. As a reaction, this creature can solidify its shards of glass into a fragile shell around its void center, giving a bonus +2 to its AC but making it vulnerable to bludgeoning. If this shell takes more than 35 points of bludgeoning or thunder damage in a single turn, its shell breaks and this ability cannot be used again.
