Batnaya the Unbreaking

Empowered Attacks. Batnaya's attacks are treated as magical for the purpose of overcoming resistance and immunity to damage from nonmagical attacks.

Trembling Ground. When angered, Batnaya's very presence unsettles the ground around him.  The ground in a 10-foot radius around Batnaya becomes difficult terrain. Each creature that starts its turn in that area must succeed on a DC 18 Strength saving throw or have its speed reduced to 0 until the start of its next turn.

Evasion. If Batnaya is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, he instead takes no damage if he succeeds on the saving throw and only half damage if he fails, provided he doesn’t have the incapacitated condition.

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

Elemental Demise. If the dao dies, its body disintegrates in a flash of fire and puff of smoke, leaving behind only equipment the dao was wearing or carrying.

Staggering Opportunity. When Batnaya hits a creature with an opportunity attack, that creature’s speed becomes 0 for the rest of the turn.

Sure-Footed. The dao has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.

Innate Spellcasting. The dao’s innate spellcasting ability is Charisma (spell save DC 19, +9 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

At will: detect magic

3/day each: enlarge/reduce, passwall, move earth, tongues

1/day each: conjure elemental (earth elemental only), gaseous form, invisibility, phantasmal killer, major image, plane shift, wall of stone

Multiattack. Batnaya makes any combination of four Punch or Kick attacks.

Punch. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: Hit: 15 (2d8 + 6) bludgeoning damage plus 3 (1d6) force damage and the target’s speed is reduced by 10 feet, to a minimum speed of 5 feet. The reduction lasts until the start of Batnaya's next turn.

Kick. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: Hit: 23 (2d12 + 10) bludgeoning damage, and the target is pushed up to 15 feet away from the guardian and knocked prone.

QUAKE Stomp. Batnaya stomps one of his feet on the ground. Any creature in a 20-foot-radius, 20-foot-high cylinder centered around Batnaya must succeed on a DC 18 Dexterity saving throw or take 33 (6d10) bludgeoning damage and fall prone. Until Batnaya uses his Stomp again or moves, the creature is restrained. While restrained in this way, the creature (or another creature within 5 feet of it) can use its action to make a DC 18 Strength check. On a success, the creature relocates to an unoccupied space of its choice within 5 feet of the colossus and is no longer restrained.

Structures, as well as nonmagical objects that are neither being worn nor carried, take the same amount of damage if they are in the cylinder (no save).

Rolling Tremor((Recharge 6).. Batnaya magically creates a wave of dirt that extends from a point on the ground within 120 feet of itself. The wave is up to 30 feet long, up to 30 feet tall, and up to 30 feet wide. Each creature in the wave must make a DC 22 Strength saving throw. On a failed save, a creature takes 58 (9d12) bludgeoning damage, has the prone condition, and is buried under dirt. On a successful save, a creature takes half as much damage only.

A buried creature has the restrained condition, has total cover, and can’t breathe. As an action, a creature buried in this way, or another creature within 5 feet of it that isn’t buried, can make a DC 17 Strength (athletics) check. On a successful check, the buried creature no longer has the prone or restrained conditions.

Earth-Shaking Movement. Batnaya moves up to his speed and sends a shock wave through the ground. Each creature on the ground within in a 60-foot-radius centered on Batnaya when he finishes this movement that is concentrating must succeed on a DC 18 Constitution saving throw or lose concentration.  This movement CAN provoke an opportunity attack. 

Parry and Riposte. Batnaya adds 4 to its AC against one melee attack roll that would hit him, provided he can see the attacker. After the attack hits or misses, Batnaya then makes one Punch attack against the attacker.

Absorb Spell. When a creature Batnaya can see within 30 feet of him casts a spell, Batnaya can absorb the spell’s energy, countering it. This works like the counterspell spell, except Batnaya must always make a spellcasting ability check, no matter the spell’s level. His ability check for this is +9. If he successfully counters the spell, he regains 5 hp for each level of the spell.

Detect. Batnaya makes a Wisdom (perception) check.

Move. Batnaya moves up to his speed without provoking opportunity attacks.

Attack. Batnaya makes a punch or kick attack

Trample (Costs 2 Actions). Batnaya moves up to 50 feet without triggering opportunity attacks, and can pass through other creature’s spaces. Each creature whose space Batnaya passes through must make a DC 18 Dexterity saving throw. On a failure, the creature takes 23 (2d12+10) bludgeoning damage and is knocked prone. On a success; the creature takes half as much damage and isn’t knocked prone. Any creature that shares Batnaya’s space when he stops this movement is pushed out of its space into the nearest unoccupied space.

 Unravel Magic (Costs 3 Actions). Batnaya targets one creature it can see within 120 feet of himself. The target must succeed on a DC 18 Constitution saving throw or take 35 (10d6) force damage, and each spell of 5th level or lower on the target ends.
