You bind yourself and one other creature to the space between planes. The target must make a Wisdom saving throw. On a successful save, nothing happens and neither of you are bound. On a failed save, a black thread binds itself to both of you, locking you in a perceived state of stasis. In reality, you both have been sucked into the space between planes and are stuck until the target makes an Intelligence check versus your spell save DC or the caster dispels the magic. If the target fails their INT check, they cannot make another for 1 minute. If they fail the next check, they cannot make another check for 1 full day. The time between check increases exponentially, to 1 week, 1 month, 1 year, 100years, 1000 years. While inside the void between planes, you can take damage but cannot fall below 1hp.
