Clay Amalgam (Crystal Level III)

Mana Crystal Core (Level 2).
A glowing crystal is embedded in the center of the grunt’s chest.

• If the Clay Grunt takes 45 or more fire damage in a single turn, its crystal becomes unstable.

• If the crystal is destroyed (called shot or critical hit,), it explodes.

Unstable Mass.
When reduced below half HP, the amalgam has advantage on Strength checks and saves, but its crystal becomes increasingly volatile.

Crystal Detonation (Level III).
When destroyed, the crystal detonates in a 15-foot radius.
Creatures must make a DC 13 Dexterity saving throw, taking
21 (6d6) force damage and being knocked prone on a failure, or half damage on a success.

Multiattack.
The amalgam makes two attacks.

Crushing Clay Fist.
Melee Weapon Attack: +6 to hit, reach 10 ft.
Hit: 13 (2d8 + 4) bludgeoning damage.

Clay Bind.
Melee Weapon Attack: +6 to hit, reach 10 ft., one creature.
Hit: 8 (1d8 + 4) bludgeoning damage, and the target is grappled (escape DC 14).

While grappling a creature, the amalgam can still make attacks with its other limb.

Clay Spear.
Melee or Ranged Weapon Attack: +6 to hit, reach 10 ft. or range 30/60 ft., one target.
Hit: 11 (2d6 + 4) piercing damage.

On a hit, the target must succeed on a DC 14 Strength saving throw or be knocked prone as the spear partially shatters inside or against them.

Pulverising Squeeze.
One creature grappled by the amalgam takes
10 (2d6 + 3) bludgeoning damage.

Clay Assimilation.
As a bonus action, the amalgam can absorb a destroyed or inert clay creature within 10 feet, gaining:

• 15 hit points, and

• advantage on its next attack roll.

This can be used once per round.
