Thessalar

Thessalar wields a +1 dagger coated with thessaltoxin poison (see appendix C).

Thessalar is accompanied by his Thessalar's Homunculus. If the Mending spell is cast on it, the homunculus regains 2d6 hit points.

Any magic item that restores hit points and can be applied to a piercing or slashing weapon (a potion, an ointment, and so forth) causes a hit with that weapon to deal extra damage to Thessalar equal to the amount the item would normally heal.

Thessalar can cast Greater Restoration if he has access to alchemical supplies.

Melee or Ranged Weapon Attack +5 to hit, reach 5 ft. or range 20/60 ft., one target. 3 (1d4 + 1) Piercing damage, and the target must succeed on a DC 15 Constitution saving throw. On a failed save, the target is affected as if by the Polymorph spell, transforming into a random Beast or a creature it has seen within the last 24 hours (as chosen by the DM). This effect lasts until the target finishes a long rest.
