Crimson Rider

Innate Spellcasting. The Rider’s spellcasting ability is Wisdom (spell save DC 17, +9 to hit with spell attacks). The Rider can innately cast the following spells, requiring no material components:

1/day each: crusader’s mantle, spirit guardians

Mounted Companion. The Rider has a Vermilion Colt monster mount.

Mount. If the Rider isn’t mounted, it can use a bonus action to mount onto the creature serving as its mount. While mounted and not incapacitated, the Rider can’t be surprised, and both it and its mount have advantage on Dexterity saving throws. If the Rider is reduced to 0 hit points while riding its mount, the mount is reduced to 0 hit points as well.

Coordinated Assault. The Rider makes a lance attack, and then its mount can use its reaction to make a melee weapon attack.

Master Rider. The Rider have advantage on melee attack rolls against any unmounted creature that is smaller than your mount. The Rider can force an attack targeted at its mount to target The Rider instead. If The Rider's mount 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.

Multiattack. The Rider makes two attacks with its Lance.

Lance. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 12 (1d12 + 5) piercing damage .
