Agility

“ Agility represents character's reflexes, fleet-footedness, jumping ability, as well as affinity towards other athletic and acrobatic activities. Among other things it affects dodge, evasion, initiative and movement points. It also allows the character to move more quietly, increasing the stealth performance. ”

Details

Agility determines how effectively your character can move and how much you can move. Agility affects your stealth skill, as well as dodge and evasion. Each point of agility above 5 increases your character's maximum movement points in combat by 3. Agility, along with dexterity, also determines your combat initiative. Some other actions (e.g. climbing over rocks to otherwise unreachable areas) also require a set score agility. No items require agility to be used or equipped.

High agility score is important for characters who rely on high mobility, attack avoidance and stealth as their defense. (As opposed to damage absorption.)
