Pathfinder 2e Spell: Elemental Missile

"One of the simplest spell-forms any magister learns to weave in their early days of training, a simple small missile or dart of elemental energy to launch as a weapon. Simple shape a shaft, a line, above your hand, a foot or so in length. Add a small triangle as if an arrow tip to the front end. Such a symbol, in such a placement above/in your dominant hand as if a dart gripped to throw, is another simple and universal symbol in the linguistics of Arcanis, as all the primordial forces seem to recognize and respond to it when made from their essence and manna."
