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

Immutable Form. The Hand of the King is immune to any spell or effect that would alter its form.

Construct Nature. The Hand of the King doesn't need air, food, drink, or sleep.

Duty before Death. (Mythic Trait; Recharges after a Short or Long Rest). If the Hand of the King is reduced to 0 hit points, it doesn’t die or fall unconscious. Instead, it regains its full health, and gains access to its Multiattack and Mythic Traits/Actions. In addition, it immediately uses its Chrysalis Action.

Multiattack (Mythic Form only).  The Hand of the King makes three Symmetrical Lance attacks, or two Launching Dash Attacks.

Symmetrical Lance. Melee Weapon Attack: +9 to hit, reach 10ft.,. Hit: 13 (2d8 + 4) Slashing damage.

Launching Dash. The Hand of the King charges forward in a 60ft. long Line (10ft. Width), forcing creatures in his path to make a DC 16 Dexterity Saving Throw or take 20 (5d6 + 2) Bludgeoning damage, and be launched 30ft. away, landing Prone. A successful save avoids all damage and knockback.

Bomb Toss. The Hand of the King tosses out three pairs of bombs randomly around the Arena. Creatures within a 10ft. sphere of the bombs must make a DC 16 Dexterity Save or take 13 (4d4 + 3) FIre damage, or half as much on a successful Save.

The Hand of the King has three Legendary Actions. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Hand of the King regains spent Legendary Actions at the start of it's turn.

Bomb Blitz. The Hand of the King uses its Bomb Toss attack.

Symmetrical Lance. The Hand of the King makes one attack with its Symmetrical Lance.

Lance Flurry (Costs 2 Actions). THe Hand of the King makes three Symmetrical Lance attacks.

Giant Slam (Costs 2 Actions). The Hand of the King leaps into the air and slams down at any point within 30ft. of where it began it's jump. Creatures in a 15ft. area of it's impact point must make a DC 18 Dexterity Saving Throw or take 18 (3d8 + 4) Bludgeoning damage. A successful save avoids all damage.

If the Hand of the King's Duty before Death trait has activated in the last hour, it can use the following actions as Legendary Actions. It also gains an additional Legendary Action, totaling it up to 4 per turn.

Chrysalis (1/Encounter, costs 4 Actions). The Hand of the King encases itself in a forcefield akin to Wall of Force, without the vulnerability to the Disintegrate spell and only covering the Hand of the King, who becomes Immune to all damage sources for 3 (1d4 + 1) Rounds. During this time, 3 (2d4 - 1) Monsters of the Beast, Fiend, or Monstrocity type appear, with a total CR of 12. Defeating these enemies destroys the Hand of the King's barrier early.

Giga Breaker (Costs 4 Actions). The Hand of the King dashes forward 10ft., then jumps into the air the same way it does during Giant Slam. It then slams itself back into the ground, forcing creatures within a 45ft. area of it's impact to make a DC 20 Dexterity Save or take 30 (6d6 + 9) Bludgeoning damage. Creatures in that area are flung up to 15ft. away and knocked Prone. The area affected by this attack becomes DIfficult Terrain.
