Shadow walk

Shadow walk was an illusion spell that helped people traveling long distances.

Description
The idea behind the spell was to travel to a transit zone between the Plane of Shadow and the Parallel plane, and then wander on this transit zone physically to the desired destination, taking advantage of an effect that caused travel distance on the transit to be a longer distance on the Prime in relation. A destination could also be to another plane. The caster could be accompanied by others, but they were under no compulsion to follow the caster around. They could strike out on their own, but the caster could also abandon them to become potentially lost.

Interestingly, the spell didn’t make usage of teleportation and thus was a safe way for long-range travel in the Underdark.

Components
Shadow walk used verbal and somatic components only.
