Cocolia

Call Of The Eternal Freeze: Cocolia's Cold Damage attacks have chances to Stun opponents. They must pass a Constitution Save to dodge the effect. The DC of the save is listed after the attack. Only one save is required per creature per attack.

On a failed save, the target creature is Frozen. Their next turn is skipped, and they have vulnerabilities to Fire and Bludgeoning damage. 

Intensifying Cold. For each enemy target Cocolia freezes, her and each of her allies gain an extra damage die on every attack. This effect is stackable, and will not expire until she dies. 

Spells. Cocolia uses CHA as her spellcasting ability. She has a +9 to hit with spell attacks.

Hoarfrost Of Eternal Isolation. Ranged Attack: +5 to hit, range 120 ft., 1 target. Hit: 22 (3d8 + 10) Cold damage. (DC 14, C)

Omen Of Everlasting Freeze. Cocolia summons 2 Ice Edges within 20ft of her. Lances share her initiative, taking their turns right after she does. They have 20 HP and an AC of 8. When a Ice Edge takes its turn, it deals 3d8 Cold Damage to hostile targets within 50 ft of it. (DC 5, C) While even a single Lance is on the field, her vulnerabilities become resistances. 

Chill Of Bone-Piercing Coagulation. Melee Attack. +6 to hit, range 25 ft., 3 target. Hit: 12 (4d8 + 4) Cold Damage to each target. Cocolia manifests twin lances of ice, slashing away at up to 3 targets. If one creature is targeted multiple times, they will still take multiple hits of damage. If a creature is targeted multiple times by this attack, their Save DC is increased by 3 per time target. (DC 10, C)

Wrath Of Winterland Saints. Cocolia enters the Charge state. Her next action will be spent using Punishment Of Endless Winter. While she is in the Charge state, she cannot move, as well as not being able to take actions or reactions.

Punishment Of Endless Winter. Cocolia invokes a massive hurricane of mana-forged ice shards. All creatures within Cocolia's line of sight must succeed on a DC 19 DEX save or take 14d10 Cold damage and be Frozen, taking half damage and avoiding a freeze on success. 

Reverberating Ice. Cocolia instantly shatters a Frozen creature. They will take 8d6 Cold damage, and any creature around them must succeed a DC 14 DEX save or take 4d6 Cold damage, taking none on a success. 

Lance. When Cocolia is targeted by an attack, she will target the attacker with Chill Of Bone-Piercing Coagulation. 

Cocolia has 5 Legendary Actions she may use at any time during another creature's turn, but she may use them on her own turn without consuming Legendary Actions. Any spent Legendary Actions regenerate at the start of her turn.

Biting Wind. Cocolia casts Cone Of Cold. If the target fails the save, they are also Frozen. 

Frozen, Banished. Cocolia casts Ice Knife. Targets hit must pass a DC 10 CON save or be Frozen.

Try To Breathe. Cocolia instantly triggers one attack from each of her lances, if any of her lances are on field.

Flutter And Sting. Cocolia casts Ray Of Frost at 3rd level.

After falling below 50% HP, Cocolia unlocks usage of her Mythic Actions. She has 5 Mythic Actions she may use at any time during another creature's turn, but she may use them on her own turn without consuming Mythic Actions. Any spent Mythic Actions regenerate at the start of her turn.

Pain, With The Blade. Cocolia immediately uses Chill Of Bone-Piercing Coagulation.

To Rend The Clouds. Cocolia uses Wrath Of Winterland Saints.
