Kobold Avenger
Legend
Often brought up on the subject of Goblins being Fey in the Monster Manual, but I feel that species such as Goblins, Hobgoblins and Bugbears which are Humanoids as PCs but have the Fey Ancestry Trait where they get Advantage on saves against and to end the Charmed condition is usually more useful to have as a PC. Being Fey is more useful against low level spells as it is outright immunity to some like Charm Person and Hold Person, but at higher levels I think having that general advantage against the Charmed condition is more useful.
