Reaction/Familiar's Reaction - Magical Ability

When you take damage from a source that your familiar can see, your familiar can use their reaction to take the damage instead. Alternatively, you can do the same for your familiar, using your reaction to take the damage dealt to your familiar from a source you can see. This damage cannot be reduced in any way.
