Clavicus unleashed

Hellish mischief. Clavicus is immune to fire damage and heals 1d6 + your charisma modifier for each enemy that you have dealt fire damage to within 60ft of it. 

Buff boi. When Clavicus is within 30ft of discordia, she gains a +3 to her spell attack modifier, and the critical hit range lowers by 1 (19 for crit). 

Spellcasting proxy. Once per turn, Discordia can cast a fire spell through Clavicus instead. Creatures that can use abilities/spells to affect the spell result must target Clavicus instead. 

Multiattack. Vile can attack twice per turn.

Confusing Horn. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 1d12 + 5 piercing and 3d6 fire damage. Target must make a DC25 wisdom saving throw or immediately use all its movement on its turn to move in a random direction. 

Fairy blast. Ranged Weapon Attack: +12 to hit, range 40/120 ft., one target. Hit: 4d6 + 3 force damage. Target is also marked and the next Attack against it is made with advantage. 

Lava pee (recharge 6). Vile releases a stream of lava pee onto a 20ft surface that lasts until the start of its next turn. Creatures that moves into this surface or are in it must make a DC25 constitution saving throw. On success they take half damage. On failure they take 10d8 damage at the start of their turns. Vile can only create one surface at a time, and the surface can vanishes as a free action. 

Puppyport (recharge 5-6). Vile uses its horn to magically teleport, alone or along with its owner, up to 60ft in a unoccupied space it can see. 

Hiccup!. When a target makes an attack or forces Vile to make a saving throw, Vile can instead make a fairy blast against that target if they are in range.
