Weave the Elder Sign

When you cast this spell, you gain 1 Contamination Level.

You weave an impossible sign from an inscrutable reality in the air inside a 30-foot cube within range. It appears for only a moment before vanishing. Each creature in the area who sees the sign must make an Intelligence saving throw. On a failed saving throw, the creature becomes blinded and stunned for the spell’s duration. On a successful saving throw, a creature is blinded until the end of your next turn. 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. When the spell ends for an affected creature, it takes 3d6 psychic damage.
