Swap is a space shifting mobility ability belonging to the R column of spells. It has two modes: Displacement and Relocate.
The swap missile instantly swaps the positions of its target and the caster. Upon reaching its maximum range, the caster will be transported to the missile without swapping anything.
Relocate instantly swaps the positions of the projectile nearest to the cast point and the caster. If a pillar is nearer than any projectile, the caster will be transported to it without swapping. For non-pillar swaps, a temporary movement speed bonus is granted.
