Ashen Creature

When Jhaeros drops to 0 hit points, he explodes in a harmless cloud of ashes, leaving nothing else behind.

Berserk

Whenever Jhaeros starts his turn with 60 hit points or fewer, roll a d6. On a 6, Jhaeros goes berserk. On each of his turns while berserk, Jhaeros attacks the nearest creature he can see. If no creature is near enough to move to and attack, Jhaeros attacks an object, with preference for an object smaller than himself. Once Jhaeros goes berserk, he continues to do so until he is destroyed or regains all his hit points.

Fire Absorption

Whenever Jhaeros is subjected to fire damage, he takes no damage and instead regains a number of hit points equal to the fire damage dealt.

Immutable Form

Jhaeros is immune to any spell or effect that would alter his form.

Magic Resistance

Jhaeros has advantage on saving throws against spells and other magical effects.

Magic Weapons

Jhaeros's weapon attacks are magical.

Actions

Multiattack

Jhaeros makes two slam attacks.

Slam

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 15 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 his next turn, Jhaeros magically gains a +2 bonus to his AC, has advantage on Dexterity saving throws, and can use his slam attack as a bonus action.
