### Feats

#### Elemental Nexus

The Greater Arcana embodies the fusion of elemental forces with unparalleled mastery, reflecting a blend of elemental attributes: Air, Earth, Fire, Water, Frost, and Thunder. Its elemental nature changes depending on its actions and its environment, allowing it to unleash a variety of elemental effects. Roll a d6 or choose an element for each of its attacks.

* Air: The Greater Arcana commands gusts of wind to buffet and disorient its foes, using Whirlwind.
* Earth: The Greater Arcana melds with rugged stone, bolstering its resilience with Stoneform Resilience.
* Fire: The Greater Arcana ignites with intense flames, engulfing enemies in searing heat with Inferno Burst.
* Water: The Greater Arcana channels the force of flowing water, wearing down opponents with Tidal Surge.
* Frost: The Greater Arcana emanates frigid cold, freezing adversaries with Frost Nova.
* Thunder: The Greater Arcana resonates with explosive energy, shaking the battlefield with Thunderclap.

#### Whirlwind (Air Only)

The Greater Arcana creates a massive vortex of wind in a 20-foot cube centered on itself. Each creature in that area must make a Strength saving throw (DC 17) or be pushed 30 feet away from the Greater Arcana and knocked prone.

#### Stoneform Resilience (Earth Only)

The Greater Arcana gains resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks. Additionally, it can use its reaction to encase itself in stone, gaining temporary hit points equal to its current hit points. These temporary hit points last until the end of its next turn.

#### Inferno Burst (Fire Only)

When the Greater Arcana hits a target with its Slam attack, it can unleash an explosive burst of flames, dealing fire damage equal to its Slam attack damage to the target and all creatures within 20 feet of it.

#### Tidal Surge (Water Only)

The Greater Arcana creates a massive wave of water that crashes over a 30-foot square area. Each creature in that area must make a Strength saving throw (DC 17) or be pushed 30 feet away from the Greater Arcana and knocked prone.

#### Frost Nova (Frost Only)

When the Greater Arcana is hit by a melee attack, it can release a freezing burst of energy. The attacker takes cold damage equal to half the damage it dealt with its attack.

#### Thunderclap (Thunder Only)

When the Greater Arcana hits a target with its Slam attack, creatures within 20 feet of the target must succeed on a Constitution saving throw (DC 17) or be deafened and take thunder damage equal to the damage dealt by the Greater Arcana's Slam attack.

### Legendary Actions

#### Essence Drain

The Greater Arcana can reach out and drain the life force from a creature within 15 feet of it. The target must succeed on a DC 17 Constitution saving throw or take 36 (10d6) necrotic damage, and the Greater Arcana regains hit points equal to half the damage dealt.

#### Elemental Grasp

As a bonus action, the Greater Arcana attempts to grasp a creature within 15 feet of it. The target must succeed on a DC 17 Strength saving throw or be restrained by the Greater Arcana's elemental energy until the end of the target's next turn. The target remains restrained for 1d3 rounds. The Greater Arcana can't use Elemental Grasp on another target until the restrained creature is no longer restrained.

#### Cataclysmic Surge

The Greater Arcana channels its elemental energies to create a cataclysmic burst of power. Each creature within 30 feet of the Greater Arcana must make a DC 17 Dexterity saving throw, taking 54 (12d8) force damage on a failed save, or half as much damage on a successful one. Additionally, each creature that fails the save is pushed 30 feet away from the Greater Arcana and knocked prone.

For a higher challenge, increase its hit points, damage, and the potency of its special abilities. For a lower challenge, decrease its hit points and the potency of its special abilities.
