Fast Healer (Feat)

You benefit greatly from your healing, be it from spells or natural healing.

Prerequisites: Con 13, Diehard (Feat), Endurance (Feat)

Benefit: Whenever you regain hit points by resting or through healing of any kind, you recover additional hit points equal to half your Constitution modifier (round down, minimum +1). At level 20, this bonus increases to the full value of your CON modifier (minimum +1).

This ability applies to both instantaneous healing and persistent healing, meaning it can be used along with any source of healing, including regeneration and fast healing.
