Empathy

Your empathy for others twists the strands of fate. You gain the ability to take on the hurt of others, at least in part.

Whenever a creature you can see within 120ft of you would suffer damage, you can choose to take on half the damage yourself as a reaction. The creature you chose will only suffer half the damage it normally would, and is aware of your action.

Your maximum HP is lowered by 1/4 of the damage suffered; this effect resets on a long rest.

If the damage you take from this feat is greater than or equal to half your maximum HP, you gain advantage on charisma checks for 10 minutes.

This feat can be use once per your CHA modifier, with a minimum of one, per long rest.
