Laurence the Inkling

As an Action, once per day you can cast Skywrite.
You can recast this with the appropriate spell slot
or Ki Points equal to spell Level. You cause up to
ten words to form in a part of the sky you can see.
The words appear to be made of ink and remain
in place for the spell’s duration. (Concentration,
1 hour) The words dissipate when the spell ends.
A strong wind can disperse the clouds and end
the spell early.
