When this spell is cast, the magic-user is able to inscribe, visibly or invisibly, his or her personal rune or mark, as well as up to six additional characters of smaller size. A wizard mark spell allows the caster to etch the rune upon stone, metal, or any softer substance without harm to the material upon which the mark is placed. If an invis- ible mark is made, detect magic will cause it to glow and be readable (which does not necessarily imply understandability). Detect invisibility, true seeing, true sight, a gem of seeing, or a robe of eyes will likewise note an invisible wizard mark. A read magic spell will reveal the maker’s intent, and an erase spell will wipe clean a wizard marked surface. The material components for the casting of this spell are a pinch of diamond dust (about 50 gp worth) and a pigment or pigments for the coloration of the mark. If the mark is to be invisible, the pigments are still needed, but the caster uses a stylus of some sort rather than his or her digit.
