When you cast this spell while negotiating with a creature the hieroglyphs light up above its head, but only the creature is unaware of the spell or the hieroglyphs.

When cast at the base level, you have a +3 to persuasion or intimidation for the duration of the negotiations. This spell at the base level costs 1 Heka Point

If it is cast at the second level, you have a +7 instead of a +3. At this level, the spell costs 7 Heka Points and you must have The Path of Heka 2 feat

If cast at the third level, you force the creature to make a Dc 19 Int Saving Throw, and if they fail they will give you anything you want (within Dm discretion). At this level, the spell costs 16 Heka Points and requires you to have The Path of Heka 3 feat.
