Skywrite

Level: 2nd
School: Transmutation
Casting Time: 1 action
Range: Sight
Components: V, S
Duration: Concentration, up to 1 hour

Description:

You cause up to ten words to form in a part of the sky you can see. The words appear to be made of cloud and remain in place for the spell's duration. The words dissipate when the spell ends. A strong wind can also disperse the clouds and end the spell early.

Notes:

• Messaging: Skywrite is useful for sending messages that can be seen over a large area, though it is not subtle.
• Visibility: The words are visible as long as they remain in the sky, making them useful for announcements, warnings, or other public communications.
• Concentration: As a concentration spell, Skywrite requires the caster to maintain focus, or the message will fade before the duration ends.
