Lay on Hands Your blessed touch can heal wounds. You have a pool of healing power that replenishes when you take a long rest. With that pool, you can restore a total number of hit points equal to your paladin level × 5. As an action, you can touch a creature and draw power from the pool to restore a number of hit points to that creature, up to the maximum amount remaining in your pool. Alternatively, you can expend 5 hit points from your pool of healing to cure the target of one disease or neutralize one poison affecting it. You can cure multiple diseases and neutralize multiple poisons with a single use of Lay on Hands, expending hit points separately for each one. This feature has no effect on undead and constructs.   Divine Smite When you hit a creature with a melee weapon attack, you can expend one spell slot to deal radiant damage to the target, in addition to the weapon’s damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 5d8. The damage increases by 1d8 if the target is an undead or a fiend, to a maximum of 6d8.   Aura of Courage and Devotion You and friendly creatures within 10 feet of you can’t be frightened or charmed while you are conscious.   Purity of Spirit Aberrations, fiends, fey, celestials, elementals and undead have disadvantage on attack rolls against you.   Mounted knight You can force attacks directed to mount to hit you. If mount is subjected to Dexterity saving throw, it takes no damage if succees and half damage if it fails.
