Time Double

You pull a mirror duplicate of yourself from another timeline.

This spell will take a spell slot to cast regardless of the ritual

This spell can only be used once in 24 hours after it ended. Any attempt to use the spell again within the 24 hours will result in an unsuccessful casting or other effects of the DM's choosing

The double shares the caster's Hit points, Spell slots, Depuffs, curses, and concentration of the spell. But can both take separate actions, make saving throws, and checks.

If either the double or the original loose or choose to drop concentration, the individual who did so becomes the original and is Stunned for 1 minute.
