Abyssal is a Rare Spirit Support from the Demonspawn faction whose value lies in a single skill that delivers both an Increase DEF and an Increase ATK buff to the whole team simultaneously — a dual offensive-defensive combination that is uncommon at this rarity level. Paired with a team-wide heal, the kit makes Abyssal a self-contained progression support, most valued in Demonspawn Faction Wars where versatile Rare supports are in short supply. He can also serve in Doom Tower secret rooms or entry-level Hydra squads. Void Gaze is not the main draw, but its team-wide reach can prove useful in compositions that rely on debuff pressure.
