Your endurance is truly beyond the pale.
Benefit: The bonus on checks and saves from Endurance increases by half your tier. You take half the damage when you fail a check to avoid non-lethal damage from a forced march, starvation and thirst, hot or cold environments, or slow suffocation.
You can sleep in heavy armor without becoming fatigued.
