Acid Absorption. Whenever the Clay Guardian is subjected to acid damage, it takes no damage and instead regains a number of hit points equal to the acid damage dealt.
Immutable Form. The Clay Guardian is immune to any spell or effect that would alter its form.
Magic Resistance. The Clay Guardian has advantage on saving throws against spells and other magical effects.
Magic Weapons. The Clay Guardian's weapon attacks are magical.
Multiattack. The Clay Guardian makes two slam attacks.
Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8+ 3) bludgeoning damage. If the target is a creature, it must succeed on a DC 12 Constitution saving throw or have its hit point maximum reduced by an amount equal to the damage taken. The target dies if this attack reduces its hit point maximum to 0. The reduction lasts until removed by the greater restoration spell or other magic.
Haste (Recharge 5–6). Until the end of its next turn, the Clay Guardian magically gains a +2 bonus to its AC, has advantage on Dexterity saving throws, and can use its slam attack as a bonus action.
Acid Cloud (Recharge 6). The Clay Guardian creates a cloud of acid which surrounds it with a 30 foot radius and a 20 foot height. Any creature within the cloud when it appears or that enters the cloud takes 9 (2d8) acid damage, with a DC 12 Constitution save for half damage. The Clay Guardian is healed for 9 (2d8) hit points as well. The cloud lasts for 2 rounds and the area of the cloud is heavily obscured.
Description
The Clay Guardian was invented by the elven wizard Jonkik Ravasatra to serve as a replacement for the clay golem, which Ravasatra regarded as crude. The Clay Guardian incorporates many features of the clay golem (albeit smaller) but is also has features borrowed from the Shield Guardian. The Clay Guardian is capable of casting a spell which surrounds it with a cloud of acid; this acid heals the guardian (see Acid Absorption, above) and damages the guardian's foes.
