Evasion can be used only if the character is wearing light armor or no armor, and is not heavily encumbered. A helpless character does not gain the benefit of evasion.

Evasion primarily helps against certain magic attacks as well as avoiding most types of trap damage. (The spell wards in Underdark adventures must be met by your Will save and cannot be evaded.) For avoiding most physical and ranged attacks, Dodge bonus chances are used.

This feat cannot be normally attained in any way except through the Heroic levels in the classes shown above. Evasion can also be gained in the form of 3 20 second activated durations with the Monk Active Past Life feat or passively with Level 5 of the Shadowdancer Epic Destiny or selected as Tier 6 in Primal Avatar Epic Destiny.
