Agility – This determines your combat abilities (how often you will hit your enemy, similar to dexterity) and some associated skills. The main skills affected are Block, Light armour and Marksman skills which will be explained in detail in the next guides.
Endurance – Controls your starting health and fatigue, or how long you are able to run and fight adequately. Your endurance is divided by 10 and added to your current health.
Intelligence – As usual, important for magic users as it sets how much magicka energy you start with. Some races have a natural modifier to magicka, which is multiplied to your intelligence and added.
Luck – Not particularly important as a primary attribute since it doesn’t really affect things in an important way. However, the chance of lock picking or creating a potion through alchemy is increased with this skill.
Personality – Allows you to persuade people, the use of some schools of magic and being able to sell and buy items at convenient prices.
Speed – Determines how fast you can move (and hence run), along with skills such as Unarmored, Hand-to Hand or Athletics. Some races have more natural speed than others.
Strength – Quite important since it allows you to carry equipment first and foremost, determining how much weight you can hold in your inventory. It also sets your health and fatigue, and allows your weapon to deteriorate if you are stronger, hence hitting with more force.
Willpower – Determines your maximum fatigue as well as your ability to cast spells related to any magic school. It also helps you resist effects such as Paralysis.
