Casters use this spell to augment the power of magic circles prepared for use with planar binding. By inscribing a circle of entrapping runes in a 10-foot radius, any magic circle cast upon the same area within the next hour is made more potent. Upon finishing the circle of runes, you must succeed on a successful Arcana check with a base DC of 25 but can be increased or reduced depending on the quality of the runes at the DM’s choosing. If the check fails, the ensnarement has no effect. There is no outward sign of this failure.
A magic circle augmented by ensnarement is more effective when used in conjunction with planar binding spells in three ways. First, the called creature is unable to be affected by teleportation spells, plane shifting, astral travel, and ethereal travel for as long as it is within the magic circle. Second, any time you are forced to make an opposed Charisma check against a creature bound into a magic circle you have enhanced with this spell, you may use your Intelligence modifier rather than your Charisma modifier. Third, you gain a +3 bonus on all checks made to overcome the spell resistance of a creature bound into the magic circle enhanced by your ensnarement.
