Pale Horse (5e Creature)
From D&D Wiki
Then I looked and saw a pale horse. Its rider’s name was Death, and Hades followed close behind. And they were given authority over a fourth of the earth, to kill by sword, by famine, by plague, and by the beasts of the earth.
Large undead, same as master
Master's Bond: The horse is bound to a single master. As an action, the horse's master can summon it, causing the horse to immediately appear in the closest unoccupied space to its master. Additionally, the horse cannot be charmed or frightened by any means.
Confer Death’s Resistance: Can grant resistance to Radiant/Necrotic to anyone riding it.
Trample: If the horse moves at least 20 feet straight toward a creature and then hits it with a hooves attack on the same turn, that target must succeed on a DC 17 Strength saving throw or be knocked prone. If the target is prone, the horse can make another attack with its hooves against it as a bonus action.
Hooves: Melee Weapon Attack: +7 to hit, 5ft. reach, one target. Hit: the target takes 2d10 + 4 bludgeoning damage plus 2d8 Necrotic damage.
