Changes

In [[15.12 Galaxy Brain]], Sam suggests that he can try to tweak the spell to open a rift to the Bad Place since they have no archangel grace. However, the Winchesters know that the only substitute that would work is Nephilim grace , which they can't do either use because of the danger of [[God]] detecting its usage and realizing that Jack is alive again.

In [[15.13 Destiny's Child]] Sam uses a variation of the spell in the demon tablet to pull Sam and Dean's [[Sam and Dean Winchester (HunterCorp)|alternate universe doubles]] -- who had been trapped between dimensions -- into their world. The main difference with in the spell involves substituting archangel grace with some of Castiel's grace. This version of the spell required the spell bowl to be set in front of where the alternate Sam and Dean were visible and did not use the Seal of Solomon. Castiel's grace worked was sufficient as the travelers were already halfway there and simply , stuck between worlds , and as such thus the rift did not require nearly as much power. The incantation for this version is the same as the one Rowena used when opening the rift to Apocalypse World.
