Crystal Ghoul

Magic Resistance. The Crystal Ghoul has advantage on saving throws against spells and other magical effects.

Parasitic Crystal. A humanoid slain by a melee attack from the crystal aberrant revives as a crystal aberrant on its next turn as the living crystal consumes the corpse

Crystalline Hide. If the crystal aberrant takes more than 10 damage in a single attack or spell, their body hardens giving them a bonus +1 AC and +1 to damage rolls but reducing their speed by 5 feet. This ability can stack. If the crystal aberrant reaches 0 speed and each time it goes below 0 speed, they are rendered incapacitated until they succeed a DC 14 Strength saving throw at the start of their turn.

 Crystal Shard Burst— On death, explode in a 30 ft. radius, dealing 3d6 piercing + 3d6 psychic (DC17 Dex save for half).
