Some spells have been made fairly obsolete with basic technology.
Using a wand (a smooth, straight wooden stick), Aston inscribes a short message onto a surface. The words he writes glow with an unnatural golden sparkle. He draws a square around them and they disappear, appearing on a surface visible to an intended target a good distance away.
Spend a Willpower (first activation each scene is free) to send the message of [[message-complexity]] size as far as [[range]]. No roll necessary. Ritual takes three rounds and is interruptible. Requires a wand to cast. Message is readable to anyone who sees it.
