Anaxa, Arbiter of Equilibrium

Equilibrium Field (Aura)

A 30 ft. aura surrounds Anaxa. Any creature that regains HP, deals damage, or casts a spell must succeed on a DC 20 Wisdom saving throw or take 4d10 force damage from the imbalance.

Immutable Form

Anaxa is immune to any spell or effect that would alter his form.

Perfect Judgment (3/day)

When a creature within 60 feet makes an attack roll, saving throw, or ability check, Anaxa can force it to reroll. He chooses whether the target uses the higher or lower roll.

Multiattack. Anaxa makes three Balance Cleaver attacks

Balance Cleaver (Melee Weapon Attack)

+13 to hit, reach 10 ft., one target.
Hit: 28 (4d10 + 6) force damage. If the target has more than half of its hit points, it takes an additional 4d10 radiant damage. If it has less than half, it takes 4d10 necrotic damage instead.

Unmake / Remake (Recharge 5–6)

Anaxa selects up to three creatures he can see. Each must succeed on a DC 21 Constitution saving throw or take 66 (12d10) force damage and be restrained in stasis until the end of their next turn. On a success, they take half damage and are not restrained.

Judgment of Equilibrium (1/day)

Anaxa releases a pulse of divine law in a 120-foot radius. All creatures must make a DC 21 Wisdom saving throw.

• On a failure, they are either reduced to half their hit points or healed to half, whichever moves them closer to equilibrium.

• Undead, fiends, celestials, and aberrations take an additional 30 radiant damage.

Balance Absolute (Mythic)

When reduced to 0 HP, Anaxa activates his Mythic Form. He regains 200 HP, changes appearance (glowing scales manifest behind him), and gains access to Mythic Actions. This can only occur once per encounter. 

Scale Rebalance

Choose two creatures within 60 feet. One is healed for 20d6 HP. The other takes that exact amount in radiant damage.

Temporal Pause

Choose a creature within 30 feet. It must make a DC 20 Charisma saving throw or be unable to act on its next turn (as if time froze for them).
