Multiattack

The fragrite makes two strike attacks.

Strike

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) bludgeoning damage. If the fragrite is in its glass form and has less than half of its total hp remaining, this attack instead deals 16 (3d8 + 3) slashing damage.

Spontaneous Explosion (Glass Form Only; Recharge 5-6)

The fragrite explodes into shards of glass, reducing its hp by 5 (2d4). Each creature within 15 feet of it must make a DC 14 Dexterity saving throw, taking 27 (6d8) slashing damage on a failed save, or half as much damage on a successful one. The fragrite then polymorphs into its sand form.
