concentration, 1 minute/mana
As two actions, you create a twisting pattern of colors that weaves through the air inside a sphere within 10 meters. The pattern appears for a moment and vanishes. Each creature in a sphere centered on that point must make a Will saving throw. If the creature can’t see the pattern, the spell has no effect on it.
A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
The spell ends for an affected creature if it takes any damage or if someone else uses an action to shake the creature out of its stupor.
