Calamity: Hald

As a Dolbushura Hald has all the innate traits of the abberations:

  Regeneration. The dolbushura regains 28 hit points at the start of its turn. If the  dolbushura takes fire damage, this trait doesn't function at the start of the dolbushura's next turn. The gabushura dies only if it starts its turn with 0 hit points and doesn't regenerate.

  Brute. A melee weapon deals one extra die of its damage when the dolbushura hits with it (included in the attack).

  Long-Limbed. When you make a melee attack on your turn, your reach for it is 5 feet greater than normal (included in the attack).

  Caustic Blood. When the gabushura takes damage of any type but psychic, each creature within 5 feet of the gabushura takes 16 (3d10) Acid damage.

Additionally Hald also has the following features:

 Rending Flails. The Flails attached to Hald`s hand have been imbued with magic. When making atacks, the glaives ignore armor and shields, hitting an enemy based on their natural AC.

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

Multiattack. Hald makes four attacks, two with its flails and two with its morningstars.

Morningstar. Melee Weapon Attack: +9 to hit, reach 10ft., one target. Hit: 16 (2d8 + 7) piercing damage.

Flail. Melee Weapon Attack: +10 to hit, reach 15ft., one target. Hit: 20 (3d8 + 8) bludgeoning damage.
