'''{{Anchor|Unending Endurance}} ([[SRD:Special Abilities Overview#Extraordinary|Ex]]):''' A Tempus paragon barely ever needs to eat or drink, and can survive for a seeming eternity. A Tempus paragon can survive without water for 1 year plus a number of extra years equal to 1.5 × his [[SRD:Constitution|Constitution]] score (not modifier). Additionally, a Tempus paragon can go without food for a number of years equal to 3 × his [[SRD:Constitution|Constitution]] score (not modifier). Also, if a Tempus paragon finds the need to begin making [[SRD:Constitution|Constitution]] checks to resist starvation, he only needs to do so once every five hours, instead of every hour. See [[SRD:Environment#Starvation and Thirst|Starvation and Thirst]] for more details.
