Homebrew Imp Species Details

Imps are found throughout the Lower Planes, either running errands for their infernal masters, spying on rivals, or misleading and waylaying mortals. An imp will proudly serve an evil master of any kind, but it can’t be relied on to carry out tasks with any speed or efficiency.

An imp can assume animal form at will, but in its natural state it resembles a diminutive red-skinned humanoid with a barbed tail, small horns, and leathery wings. It strikes while invisible, attacking with its poison stinger.

Shapechanger. The imp can use its action to polymorph into a beast form that resembles a rat (speed 20 ft.), a raven (20 ft., fly 60 ft.), or a spider (20 ft., climb 20 ft.), or back into its true form. Its statistics are the same in each form, except for the speed changes noted. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Devil's Sight. Magical darkness doesn't impede the imp's darkvision.

Magic Resistance. The imp has advantage on saving throws against spells and other magical effects.

 

Imps can use its tail to deliver a dose of poison. This deals additional poison damage of 3d4 + your Constitution modifier on top of the stingers piercing damage. The target then needs to make a Constitution saving throw, (DC = 8 + Proficiency + Constitution) taking half damage on a save or full damage and be poisoned for 1 minute on a failure. This can be done a number of times equal to your Constitution modifier recharging after a long rest. Alternatively an imp can milk the poison from its own tail to use it on a different weapon. The poison stays potent for one hour if used in this way. An imp is always immune to the effects of its own poison.
