### Feats

#### Elemental Nexus

The Arcana embodies the essence of multiple elemental forces, 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 Arcana manifests swirling winds that buffet and disorient its foes. Its Slam attack deals bludgeoning damage, and it can use the *Whirlwind* ability.
* Earth: The Arcana's form solidifies into rugged stone, bolstering its resilience. Its Slam attack deals bludgeoning damage, and it can use the *Stoneform Resilience* ability.
* Fire: The Arcana ignites with fierce flames, engulfing its enemies in searing heat. Its Slam attack deals fire damage, and it can use the *Inferno Burst* ability.
* Water: The Arcana channels the power of flowing water, wearing down its opponents with relentless force. Its Slam attack deals bludgeoning damage, and it can use the *Tidal Surge* ability.
* Frost: The Arcana emanates frigid cold, freezing its adversaries in their tracks. Its Slam attack deals cold damage, and it can use the *Frost Nova* ability.
* Thunder: The Arcana resonates with thunderous energy, shaking the battlefield with sonic booms. Its Slam attack deals thunder damage, and it can use the *Thunderclap* ability.

#### Whirlwind (Air Only)

The Arcana creates a swirling vortex of wind in a 15-foot cube centered on itself. Each creature in that area must make a Strength saving throw (DC 15) or be pushed 20 feet away from the Arcana and knocked prone.

#### Stoneform Resilience (Earth Only)

The 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 Arcana hits a target with its Slam attack, it can unleash a burst of flames, dealing fire damage equal to its Slam attack damage to the target and all creatures within 10 feet of it.

#### Tidal Surge (Water Only)

The Arcana creates a wave of water that crashes over a 20-foot square area. Each creature in that area must make a Strength saving throw (DC 15) or be pushed 20 feet away from the Arcana and knocked prone.

#### Frost Nova (Frost Only)

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

#### Thunderclap (Thunder Only)

When the Arcana hits a target with its Slam attack, creatures within 15 feet of the target must succeed on a Constitution saving throw (DC 15) or be deafened and take thunder damage equal to the damage dealt by the Arcana's Slam attack.

### Actions

#### Slam

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 4) elemental damage (based on elemental type).

#### Essence Drain

The Arcana can reach out and drain the life force from a creature within 10 feet of it. The target must succeed on a DC 15 Constitution saving throw or take 24 (7d6) necrotic damage, and the Arcana regains hit points equal to half the damage dealt.

#### Elemental Grasp

As a bonus action, the Arcana attempts to grasp a creature within 10 feet of it. The target must succeed on a DC 15 Strength saving throw or be restrained by the Arcana's elemental energy until the end of the target's next turn. The target remains restrained for 1d3 rounds. The Arcana can't use Elemental Grasp on another target until the restrained creature is no longer restrained.

#### Variant

The Arcana's challenge rating can be adjusted by changing its hit points, damage, and the potency of its special abilities. 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.
