Borauga's Enemy Binding

A spell created by the vengeful, yet extremely cowardly enchanter, Borauga Boermann, the spell makes it practically impossible to for a specific humanoid target to damage the caster with either physical or magical attacks. If the caster attacks the target, the spell ends immediately.

If the effigy used for casting is destroyed, the spell ends immediately.

For every caster level, add 10 feet to the range of the spell.

A Wisdom saving throw of 10 + caster level negates the spell. 

For every one spell level this spell is cast above 5, the spell lasts for another seven days unless interrupted.

If the caster dies before the spell ends, the spell deactivates instantaneously. 

This spell is not class-locked. Any entity able to comprehend and carry out the components stated from either a spell tome or taught by one who knows this spell already can use it. Common folk who come across this spell use it to aid in their daily task for both personal and impersonal gain depending on the alignment of the caster.
