Corrupted Hugo

Innate Spellcasting: His innate spellcasting modifier is his charisma modifier. 

1/day: Inflict wounds 

At-Will: Mold Earth [5th Level]

Multiattack. Hugo makes two slam attacks.

Slam. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: (3d10 + 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

Forceful Hurl. A creature that is grappled by the corrupted Hugo is thrown in a straight line for sixty feet. Any creature in the straight line must succeed on a DC 18 Dexterity saving throw or take 11 (2d6) bludgeoning damage. The thrown creature must succeed on a DC 18 Dexterity saving throw or take 15 (2d6) bludgeoning damage and land prone. On a success, the target takes a fourth of the damage and does not become prone. 

Amalgamate: Hugo increases his armor class by his constitution modifier once per short rest.
