(*spell that works with Alchemical Savant) (**Tavros casts this spell on himself before combat)

Alchemical Savant. When Tavros casts a spell, he gain a bonus to one roll of the spell. That roll must restore hit points or be a damage roll that deals acid, fire, necrotic, or poison damage, and the bonus equals his Intelligence modifier.

Chemical Mastery.  Tavros can cast the following spells innately without expending a spell slot or providing material components:

1/day:  heal, greater restoration

Corrosive Form.  Tavros' body has been transformed by centuries of exposure to powerful reagents.  A creature who touches Tavros or hits him with a melee attack while within 5 feet of Tavros takes 5 (1d10) acid damage.  It can take this damage no more than once per turn.

Magic Items.  Tavros wears bracers of defense, a amulet of proof against detection and location, and a mantle of spell resistance.  He has advantage on saving throws against spells, and cannot be targeted by divination magic or perceived through magical scrying sensors.

Multiattack.  Tavros casts one cantrip and uses his Hurl Potion ability

Hurl Potion. Ranged Weapon Attack.  +7 to hit.  Range 20/60.  Hit: 6 (1d4+4) piercing damage, and the target must roll a d6, with the following effects applied depending on the result:

1. Deadlift Drops:  The target must succeed on a DC 18 Strength saving throw or become restrained until the end of its next turn as its limbs drastically increase in weight.  While restrained in this way, the targets melee attacks and unarmed strikes deal an extra 10 (4d4) bludgeoning damage on a hit.
2. Jelly Legs Juice.  The target must succeed on a DC 18 Dexterity saving throw or fall prone;  it cannot stand up until the end of its next turn.  While prone, the targets limbs flail violently.  Any creature that moves within 5 feet of the target or starts its turn there must succeed on a DC 18 Dexterity saving throw or take 5 (2d4) bludgeoning damage from the flailing limbs
3. Snoring Solution.  The target must succeed on a DC 18 Constitution saving throw or fall unconscious until the end of its next turn.  While unconscious, the target snores violently.  Creatures who move within 15 feet of the target or start their turn there must succeed on a DC 18 Constitution saving throw or take 5 (2d4) thunder damage.
4. Terror Tea.  The target must succeed on a DC 18 Wisdom saving throw or become frightened of all creatures within 30 feet of itself until the end of its next turn.  While frightened, the target's speeds are doubled.
5. Charming Cordial.  The target must succeed on a DC 18 Intelligence saving throw or become charmed by Tavros until the end of its next turn.  While charmed, the target harbors intense jealousy towards Tavro's allies, and has advantage on attack rolls against them
6. Ethereal Elixer.  The target must succeed on a DC 18 Charisma saving throw or be banished into the ethereal plane until the end of its next turn.  While the target is banished, 1d4+1 shadows appear in the nearest unoccupied spaces to the target.  The shadows act on the targets turn, attacking any nearby creatures.  They disappear when they die or when the banished creature returns to the material plane.

Tavros can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Tavros regains spent legendary actions at the start of its turn.
