Ancient God Script (Bind)

By some means you managed to learn and copy the magical circle of the Ancient God Script (Bind). whether that be through a magic item that has the spell inscribed on it or from a Spellbook or through force of will. 

Upon casting Ancient God Script (Bind). A 10 foot magic circle crackling with the energy of your magic appears under the targeted creature. The target creature must make a contested skill check using the target creature's spell casting ability modifier against the caster's spell attack bonus. (Note: if the target creature has no casting ability the target creature must roll a flat d20 no modifiers to contest.) If the target creature fails the contested check the target creature is immediately bound in magical chains restraining the target creature. In addition the target creature is unable to cast magic or use any class/race abilities for the duration of the spell. 

If the target is not a creature the spell automatically succeeds and is affected by the effect of (Bind). 

Alternatively you can enchant an item with this circle. Doing this allows the enchanter to apply the main affect (Bind) to the wearer or wielder of the item. Another benefit of enchanting is the ability to modify the Spell Potency, Spell Activation, Circle Size, and Spell Duration parameters with Modifier Circles.
