Crowdin the Cruel

Mounted Combat. Crowin has advantage on melee attack rolls against any unmounted creature that is smaller than his mount. Crowdin can force an attack targeted at your mount to target you instead. If Crowdin's Nightmare is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails. Crowdin cannot be knocked free of his mount.

Dreadful Aura. Doomed souls and spirits flit about Crowdin at all times, and he radiates magical darkness in a 30 foot radius. When an enemy enters the aura’s area for the first time on a turn or starts its turn there, it must succeed on a DC 17 Wisdom saving throw or be frightened of Crowdin for 1 minute. If a frightened target ends its turn more than 30 feet away from Crowdin, the target can repeat the saving throw, ending the effect on itself on a success. A frightened target that starts its turn within 30 feet of Crowdin takes 4d10 psychic damage. Good aligned Paladins' auras do not function within Crowdin's Dreadful Aura.

Multiattack. Crowdin makes three attacks, using The Darkflame.

The Darkflame. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 15 (1d8 + 11) slashing damage plus 22 (5d8) force damage.

Rebuke Faith. When a good aligned Paladin that Crowdin can see heals a creature, Crowdin cause the healer to take necrotic damage equal to half of the hit points healed. This damage is not affected by weakness, resistance, or immunity. Crowdin the Cursed gains temporary hit points equal to the damage dealt.

Dread Lord. Crowdin performs a melee spell attack (+9 to hit) to a single target within his aura. The doomed souls flitting about him deal 3d10+3 necrotic damage to that target.

Telekinetic Reprisal. When Crowdin takes damage from a creature within 10 feet of him, he can emanate telekinetic energy. The creature that dealt damage must make a Strength saving throw (DC 17). On a failed save, the creature takes 2d8 force damage and is pushed up to 10 feet away from him. On a successful save, the creature takes half as much damage and isn’t pushed.
