Sneak Attack (1/Turn). Imoen deals an extra 14 (4d6) damage when she hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of Imoen that isn't incapacitated and Imoen doesn't have disadvantage on the attack roll.
Spider Climb. Imoen can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Sunlight Sensitivity. While in sunlight, Imoen has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Boo has always liked Imoen. She's like his big sister. Though not as furry and a lot smaller.
