As two actions, a creature that you can touch or see within 20 meters must make a Will saving throw.

On a failed save you wrest control of a spell that the target is concentrating on. For the duration the creature does not need to concentrate on the spell as you are now concentrating on it (as part of the concentration of this spell). Once you wrest control of the spell from the target, you have several options:

• Allow the spell to function as normal.
• Decide how the spell fulfills its function each round.
• Retarget the spell on yourself or centered on a new point within 20 meters.
• End concentration on this spell, ending the co-opted spell.
