Spell: Throw Shade (a Sept-umbra creation) (Patreon)

Use your words to darken the world for a creature and cause it to doubt its own abilities.

This was created for day 12 of Sept-umbra.

2023-05-04: Updated the spell a little. Using an action no longer gives a new saving throw, it simply ends the spell (and the target's turn). The original version was just a little too strong for 1st level.
