Amalgam of Earth

Empowered Attacks. Amalgam of Earth's slam attacks are treated as magical for the purpose of bypassing resistance and immunity to nonmagical weapons.

Innate Spellcasting. Amalgam of Earth’s innate spellcasting ability is Charisma (spell save DC 20, +12 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

At will: meld into stone, move earth, wall of stone

Legendary Resistance (3/Day). If Amalgam of Earth fails a saving throw, it can choose to succeed instead.

Magic Resistance. Amalgam of Earth has advantage on saving throws against spells and other magical effects.

Siege Monster. Amalgam of Earth deals double damage to objects and structures with his melee and ranged weapon attacks.

Multiattack. Amalgam of Earth makes two slam attacks.

Slam. Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage.

Boulder. Ranged Weapon Attack: +6 to hit, range 500 ft., one target. Hit: 46 (7d10 + 8) bludgeoning damage. If the target is a creature, it must succeed on a DC 23 Strength saving throw or be knocked prone.

Summon Elementals (1/Day). Amalgam of Earth summons up to ten earth elementals. Summoned elementals have maximum hit points, appear within 100 feet of Amalgam of Earth, and disappear if Amalgam of Earth is reduced to 0 hit points.

Amalgam of Earth can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Amalgam of Earth regains spent legendary actions at the start of his turn.

Illuminating Crystals (Costs 1 Action). Amalgam of Earth's crystalline protrusions flare. Each hostile creature within 30 feet of Amalgam of Earth becomes outlined in orange light, shedding dim light in a 10-foot radius. Any attack roll against an affected creature has advantage if the attacker can see it, and the affected creature can’t benefit from being invisible.

Shard Shield. Amalgam of Earth sends dozens of large rocky shards from its form to an ally within 100 feet of it. Until Amalgam of Earth's next turn damage dealt to this ally is instead dealt to Amalgam of Earth.

Reinforce (Costs 3 Actions). Amalgam of Earth absorbs stone and earth within 50 feet of itself, healing for 5d10+10 hit points and gaining resistance to magical and non-magical damage until its next turn.
