Moonglow Symbol

This spell enables the caster to draw a glowing symbol in the air or on a solid surface. The symbol is drawn with pure water, which vaporizes from the drawing finger during the spell. The symbol glows with a faint, silver-blue light, like moonlight. Until dispelled, the glow can be seen only in darkness, and is otherwise invisible. The symbol consists of radiant air, and cannot be moved or modified except by casting another moonglow symbol spell on it. The glowing figure cannot bear any magical powers, such as those of a glyph or symbol spell, nor can it be linked to any other magic via a spell trigger or other magic.

A moonglow symbol spell can be used to write messages and even to set down sigils and runes, but these are without magical power. In some cases, wizards have deliberately used this limitation to draw harmful runes or glyphs for recognition purposes or as warnings to keep away. Symbols created with this spell cannot turn, animate, or react, but can be fashioned into pointing hands, masks that resemble human faces, and other shapes that might convey meaning.

A moonglow symbol remains stationary unless cast on an object, whereupon it moves with that object. If the object is destroyed, the symbol is also. In the dark, moonglow symbols give off enough light to read by.

Notes: Uncommon for geometers; otherwise rare. Originally from the Forgotten Realms setting.
