Cornmuffin Sanctuary relocates the group to another location, can fail, doesn’t work on encumbered targets, and isn’t available until level 55.
Ritual of Escape is available at level 40 and clears threat without relocating the group, prevents aggression, conceals everyone from living and undead enemies, restores health and mana, and grants see invisible. That’s far more than an evac alternative, and it is available 15 levels earlier.
They just don't compare to me, so I was offering something that might help balance things out.
