Description
You employ mystical geometry to draw a sigil of matter on a surface within the area of effect. The length of time it takes to draw the sigil with your maleficence is equal to 1 round per MP invested into the spell; for every MP invested into the sigil's drawing, the next spell cast within its boundaries has its targets increased by a multiple of the MP spent. The sigil persists for 24 hours or until triggered, and you may draw a sigil of matter within a pre-existing sigil of matter. If the spell is cast within nested sigils, the number of targets is multiplied by the MP spent on each sigil. All sigils triggered in this way are consumed by the casting of the spell enhanced by their geometry.
