Bonded Familiar- Anika Arryn. Chip may be summoned by Anika using the Find Familiar spell, and counts as her familiar to all intents and purposes. If his hit points are ever reduced to zero, when Anika uses Find Familiar again, he is resurrected.
Devil's Sight. Magical darkness doesn't impede Chip’s darkvision.
Magic Resistance. Chip has advantage on saving throws against spells and other magical effects.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one.
Invisibility. Chip magically turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the imp wears or carries is invisible with it.
