Forbidden Obelisk

Before paper, man wrote upon stone of the things that could not be spoken using a script that cannot be misunderstood. Many could not handle the truth, and wrote in blood.
You summon forth 10-foot-tall pillar 5 feet across covered in runic inscriptions from the depths of the earth. Any creature that can see and moves into a space within 10 feet of the obelisk cannot help but read from it. The reader must make a Wisdom saving throw. If they succeed, they gain advantage on Wisdom ability checks and saving throws for one minute. If they fail, they are struck blind for one minute. Once a creature has read from a forbidden obelisk, they cannot do so again until at least one hour has passed.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the duration of the blindness or advantage increases to 10 minutes.
