You can only cast Evasion with a weapon equipped. What if I swap weapons or get disarmed during evasion? When you switch weapons whilst under the evasion spell, a check is performed on each attack of your current weapon, meaning if you start evading with a one handed weapon, and switch to a 2 handed weapon, you will receive the evasion bonus of a 2 handed weapon whilst the 2 handed weapon is equipped.

If you're disarmed you will not be able to evade, the evasion buff however will remain because if you re-arm you will continue to evade.
