Here's my take on evocation maneuvers:
You resist the power of the maneuver, not the targeting/control roll
example:
You throw a power 5, maneuver and get a 7 on your control roll. The person you are hitting with the maneuver resists the power (5) and not the control (7)
Aspects generated by evocation maneuvers are fragile or sticky, as normal.
Regular rules:
If you match their defense, you get a fragile aspect. If you exceed their defense, you get a sticky aspect.
Duration added to maneuvers denotes the number of turns that the person with the applied aspect is unable to take an action to remove the aspect
Example:
I hit someone with a power 4, duration 3 blinding maneuver. Their defense is 3, so they get the sticky aspect of blinded. Normally, they would be able to take an action to remove the aspect any time they wanted to. But the extra duration of 3 means that they can't do this until the 3 turn duration is up.
