A maneuver should not take an opponent out. If the spell is creating an aspect through a maneuver, then it's something which interferes with the target's actions, but doesn't completely prevent them. Someone with the sticky aspect FROZEN can still move, they're just slower, because their muscles are stiff and they're numb with cold.
If a spell is actually supposed to take an opponent out of the combat, it needs to be an attack which inflicts stress. In that case, it doesn't create an aspect in the same way that a maneuver does. If the opponent reduces their stress by taking consequences, then they gain aspects in the form of those consequences, and the duration of those aspects follows the consequence rules, instead of the evocation rules. If the opponent takes more stress than they have in their track, and doesn't/can't reduce it below that with consequences, then instead of consequences or an aspect, they're taken out. At that point, they should no longer be the target of any combat actions: they're out of the combat.
In any case, aspects don't affect skill rolls unless they're tagged or invoked. If you want to create an effect which persistently affects a target's actions without tagging or invoking, what you want is not an aspect, it's a block.
