Gate Seal (Reversible)

Planewalker's Handbook Version

The primary use of gate seal is as a more powerful, longer-lasting version of gate ward, allowing the mage to close two connecting gates on the same plane. The only difference lies in the duration of the spell.

Gate seal has a secondary benefit, however, which is applicable only on the plane of Acheron, where the spell was originally developed. When cast on an Acheron battlefield, all cubehopper spells (see 6th-level spells, below) fail in the area of the ongoing battle. It also prevents teleportation or other magical transports that would take creatures from the cube and move them to another cube on the plane. Gate seal doesn't prevent a body from leaving the plane altogether by plane shift, teleport without error, or similar magic.

The material component of the spell is a bar of steel.

The reverse of this spell, break gate seal, automatically dispels a gate seal cast by any wizard.

The material component for this spell is an iron spike.

Wizard's Spell Compendium Version

The gate seal spell is a more powerful version of gate ward. It temporarily shuts down any one gate between the cubes of Acheron. If the spell is cast just as a creature enters a gate, the creature vanishes into the gate and immediately reappears out of it, effectively going nowhere. A sealed gate displays the seal of the wizard who cast the spell. The gate seal of a wizard who has no personal sigil displays the face of the caster. The gate seal lasts for 1 turn per caster level, and when cast on a battlefield, all cubehopper spells fail within the area of the ongoing battle.

The material component of the spell is a bar of steel.

The reversed form, unseal gate, only negates the gate seal and gate ward spells. Its material component is a twig, which is snapped as the spell is completed.

Notes: Uncommon in the Planescape setting; otherwise, very rare (and useful primarily on Acheron).
