Fey Skin

Your connection to nature allows you to recover quickly and grants you great health, though in exchange you suffer the same weakness to cold iron that plagues many fey. Whenever you take damage from a weapon made of iron (most metal weapons that aren’t specifically made of a different metal), you take additional damage equal to half your level. In exchange,you gain the following benefits:

• Your hit point maximum increases by an amount equal to your level. Whenever you gain a level thereafter, your hit point maximum increases by an additional 1 point.
• Every hour, you regain hit points equal to your level
