D&Dtools

Benefit

You gain a +4 bonus on all Strength and Constitution ability checks, but not on Strength- or Constitution-based skill checks. You also gain a +4 bonus on the following checks and saves: Swim checks made to resist nonlethal damage, Fortitude saves made to avoid nonlethal damage from hot or cold environments, Fortitude saves made to resist damage from suffocation, and grapple checks made to escape a grapple or pin. Also, you can sleep in medium armor without becoming fatigued.

Special

A kobold who would gain Endurance as a bonus feat can choose Kobold Endurance in its place. Kobold Endurance counts as the Endurance feat for the purpose of meeting a prerequisite for a feat, prestige class, or special ability.

Normal

A character without this feat who sleeps in medium armor is automatically fatigued the next day.
