“Endurance is a measure of your overall physical fitness. A high Endurance gives bonuses to health, environmental resistances, and the Big Guns and Unarmed skills.”

Every point of Endurance gives you 20 Hit Points, a fairly significant amount considering you gain 10 Hit Points per level (excluding the first) added on to a base of 100. This bonus is retroactive-should you gain more Endurance later, you’ll find yourself burdened with an extra 20 Hit Points. You also gain a +2% bonus to your Radiation Resistance and a +5% bonus to your Poison Resistance for every point of Endurance above one, which is retroactive as well. This is a fairly good attribute, and it gives bonuses to two skills… even though Big Guns kind of sucks. Since all the bonuses are retroactive, there’s no call to put more points into it when you begin than you absolutely need. Six is a good score to start out with.
