Dedicated Healer

You have become an expert in the art of healing wounds in a battlefield.

• Whenever you cast a spell or use a healing class ability that allows you to retrieve hit points, you gain an hit points equal to the spells normal healing effect + 1d4. The healing of this function increases as you gain level, level 5 (1d6), level 11 (2d8) and level 17 (4d8).
• Your knowledge in the healing and regeneration of wounds is so great that if the amount healed is equal to or greater than the damage that made the wound, it will not leave traces of damage, such as scars or discomfort. (This ability does not regenerate severed limbs).
• If any member of your group within 10 feet of you is struck with a melee attack,  you may use your reaction, to cast a spell of up to 3rd level with a casting time of 1 action or less (this includes a bonus action), that you can cast that allows for the recovery of Hit Points (i.e: cure wounds, healing word, mass healing word). You must have a spell slot available to use this ability, and may not be prevented from casting a spell. Once used, you can not use this feature again until after a long rest.

Prerequisites: Wis 14 or higher, and the ability to cast at-least one "Healing" spell
