Crystalline Abomination

Crystal Harvest: When defeated, it can release a wave of shards that can blind players and inflict heavy damage if they are too close.

Weakness:

Extremely vulnerable to magic that harnesses the power of light or holy energy, which can disrupt its dark powers and shatter its form.

Reward:

Abomination's Core: A powerful crafting item that allows players to create the most potent glass weapons, capable of piercing through armor.

Crystalline Fragments: These can be used to enhance armor, granting it reflective properties that can return damage to attackers and reduce damage taken from sharp objects.

Abilities:

Glass Vortex: The Crystalline Abomination can create a vortex of glass shards that pulls players toward it while dealing continuous damage. Players caught in the vortex are unable to escape until the effect ends.

Soul Shatter: It unleashes a devastating blast of energy that shatters nearby glass blocks, dealing massive area damage and causing players to stagger.

Reflection of Terror: The abomination can reflect damage dealt to it back at the attacker, forcing players to rethink their strategies when fighting it.
