Wpn/Arm Prof: an unyielding soul gains no new weapon or armor proficiencies.

Vigor (Ex): The unyielding soul may spend one minute to regain the temporary hit points granted by the Azure Toughness feat.

Additionally, the unyielding soul gains twice as many temporary hit points from the Azure Toughness feat.

Resilience (Ex): At each level, the unyielding soul gains one of Cerulean Fortitude, Cerulean Reflexes, or Cerulean Will. If the unyielding soul already possesses these feats and cannot select another, they may select any other feat they qualify for instead.

Additionally, while the unyielding soul possesses temporary hit points, they are treated as having a number of points of essentia invested in Cerulean Fortitude, Cerulean Reflexes, and Cerulean Will equal to half the essentia invested in the Azure Toughness feat, rounded down. This stacks on top of any essentia invested into these feats.

Vitality (Ex): While an unyielding soul of at least 2nd level possesses temporary hit points, they gain a bonus on Str, Dex, and Con checks and with all skill checks made with the following skills; Balance, Climb, Concentration, Jump, Ride, Swim, and Tumble equal to the essentia they have invested in the Azure Toughness feat.

Additionally, the unyielding soul may choose to, as a move action, gain fast healing 1 as long as they possess temporary hit points. At the end of a round in which they benefited from this fast healing, they lose one temporary hit point and take one point of nonlethal damage*. The fast healing granted by this ability does not heal nonlethal damage, instead only healing lethal damage. The unyielding soul may end this effect as a move action.

Hardened (Ex): While an unyielding soul of at least 3rd level possesses temporary hit points, they gain a bonus to their natural armor equal to the essentia they have invested in the Azure Toughness feat.

Additionally, as long as they possess temporary hit points, the unyielding soul gains Damage Reduction equal to half the essentia they have invested in the Azure Toughness feat, rounded down. This damage reduction is not overcome by anything (DR/-) and stacks with other sources of similar damage reduction (such as that from a Barbarian).

*Vitality's secondary effect essentially heals one hit point at the cost of one damage to your temp hp and one point of nonlethal damage. It is technically a net loss (2 damage for one point of healing), but allows the unyielding soul to heal over the course of hours rather than days without magical aid.
