Crack reality

Break apart the reality in front of you, creating a rift the mirror dimension. This rift is one-way. It is treated as a mirror zone but does no effect the material plane. As a bonus action, anyone in the zone can make an INT(Arcana) check(DC:10) to trigger an event. The caster makes the check with advantage. If the check is failed, they take 1d12 piercing damage and get teleported up to 15 feet away. If they fail by 5 or more, they take 1d12xclass level slashing damage and teleported up to 50 feet away. On a natural 20, you may choose the effect. Any illusions cast in this area are treated as having a physical form. Any spellcaster can use an action to make a INT(Arcana) check(DC:13) to make a rift leading to the same location on the material plane. Anyone that dies in the mirror dimension cracks apart and drifts away.
