Codex Endurance (3.5e Feat)

Good-Look: You were more worried about having a good look than building up actual endurance. You gain a +2 bonus on charisma-based checks against creature of similar bodyshape as you (in the case of humans; most humanoids, giants and humanoid shaped outsiders).

Iron Guts: You gain a +4 bonus against poisons and disease. You halves the penalty of being sickened and you may take a single standard action instead of a move action while being nauseated.

Strongman: You double your carrying capacity. You can wield weapon of a single size category bigger than you normally could, however you are limited to a single attack (even on a full-attack action) with it, cannot take attacks of opportunity with it and if your base attack bonus was lower than 6 you are staggered after each attacks.

Well-Rationed: Your body handle lack of drink, food and sleep better than than the average. You can go three time as long without sleep and twice as long without food before suffering any consequences. You also recover from fatigue and exhaustion after an hour of not doing any strenuous activities instead of a full rest.
