Sword of Sealing

Your spiritual power pierces both body and soul, pinning your foe in place. Make a melee Strike with a one-handed, agile, or finesse weapon, or your fist unarmed attack. On a successful hit, the target must succeed at a Fortitude save against the higher of your class DC or your spell DC, or become Immobilized. The target can end this immobilization with a successful Escape attempt using the higher of your class DC or your spell DC as the Escape DC.
