Lord of the Rings (5E)
The Path of the Totem Warrior gains a new totem option: the Horse. This totem focuses on speed and endurance.
Horse. As long as your mount isn’t wearing armor, it adds its Constitution modifier to its AC. While you’re raging and mounted, your mount has advantage on Strength checks and Strength saving throws, and resistance to bludgeoning, piecing, and slashing damage. The spirit of the horse makes your mount ferocious and enduring.
ASPECT OF THE BEAST
Horse. You gain the endurance of a horse. You gain advantage on saving throws to resist exhaustion, and your mount can move at full gallop for an additional hour.
Horse. While you’re raging and mounted, you can use your bonus action on your turn to knock a creature smaller than your mount prone when you hit it with a melee weapon attack.
