You are especially hard to kill. You can turn aside the heaviest hits in battle, your wounds automatically stabilize when grievously injured, and you can remain conscious and continue to act even at death's door.
Prerequisites: Level 1, Endurance (Feat)
Unlocks: Fast Healer (Feat), Fortified Armor Training (Feat), Stalwart (Feat),
Stalwart, Improved (Feat), Survivor (Feat), Tenacious Survivor (Feat)
Benefit: When your hit point total is below 0, but you are not dead, you automatically stabilize, though your current hit point total remains unchanged (negative). You may act as if you were Staggered for one round after your hit points are brought below zero, though you immediately fall unconscious at the end of that round if your hit points remain negative.
Special: Once per day, you may choose an attack and take half damage from it. This may be declared after the damage is rolled, and is applied before any mitigation is applied (such as DR or ER). At 20th level and above, you may do this once per encounter.
