Lay on Hands

You have a pool of healing power that
replenishes when you take a long rest equal to
your paladin level x 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.
