Alchemical Homunculus

12 + your Intelligence modifier

5 plus 5 times your Alchemist Level (it has a number of Hit Point Dice [d4s] equal to your Alchemist Level)

If the homunculus is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the homunculus instead takes no damage if it succeeds on the save and only half damage if it fails. It can't use this trait if it has the Incapacitated condition.

Melee Attack Roll: +2 plus your Intelligence modifier, reach 5 ft. Hit: 1 Piercing damage, and the target is Poisoned for 1 minute. If the attack roll exceeds the target's Constitution score by 5 or more, the target falls Unconscious until it takes damage or another creature uses an Action to shake it awake.
