Range 30 feet
Target 1 creature
Saving Throw basic Will
You place a psychic lock in a foe's mind that prevents it from a specific action. Choose "Strike," "Stride," "Cast a Spell," or a specific action you know the creature to have (such as a dragon's magic breath). If the creature attempts that action on its next turn, it must surmount your lock to do so, causing it to take 2d6 mental damage (with a basic Will save). The target is then temporarily immune for 1 minute.
Heightened (+1) The damage increases by 1d6.
