Duration:  1 day per level
Casting Time:  1 turn

Saving Throw:  None

Upon casting this spell, a purple glowing rune will appear on the body of the creature. The rune will have to be traced on the body by the caster, so the place is up to the caster. This rune can only be removed if the caster so wishes, someone erases it (cf. the spell with the same name), or a successful dispel magic or such is cast. While the rune glows on the body of the caster, the caster is immune to normal weapons as per potion of invulnerability.
