By means of this spell, the caster creates a magical portal to another location on the same plane that the wizard has previously visited. The wizard and other individuals can cross freely between one side of the portal and the other for the duration of the spell.
The gateway appears as a vertical disk 10 feet in diameter. Through the portal on one side, the terrain beyond can be clearly seen. The other side of the disk is a smooth gray surface. The portal cannot be called into being in the same space as another object but can be placed against a wall or other flat surface.
Creatures can pass through freely from one side of the portal to the other, but nonliving material cannot unless brought by living creatures. Each side of the gateway maintains its own environment, so that opening a portal into a live volcano or at the bottom of the ocean poses no danger to someone on the other side unless he chooses to cross into such a deadly area.
The gateway can only be cast into areas that the wizard has himself visited. In addition, there is a success rate dependent on distance from the source.
| Within 100 miles of the area | 100% success |
| Within 500 miles of area | 50% |
| On different planet | 10% |
| In different solar system | 5% |
Failure indicates that no such portal can be opened. Gateway portals cannot open into other planes of existence or be cast while on any plane other than the Prime Material.
A gateway can be dispelled by the caster at will, by a successful dispel magic, or by the spell duration elapsing. Any living thing caught in the portal as it collapses must make a Dexterity check or be sliced between two different locations, presumably killed instantly.
The material component of this spell is a handful of earth or the equivalent from the caster's location.
