Create portal

Create portal was an alteration spell used by spelljamming mages to open a temporary opening in a crystal sphere to pass into or out of the phlogiston.

Effects
If the spellcaster was within 300 feet (90 meters) of the surface of a crystal sphere, this spell could cause an area of the sphere 100 feet in radius (30 meters) to become immaterial, allowing a spelljamming vessel to pass through. Such a portal would last for at least a couple minutes or as long as almost a quarter of an hour before dissipating, giving a ship plenty of time to pass through safely. However, if the duration ended while a ship were in transition&mdash;or if the spell's magic was dispelled&mdash;the reformation of the wall of the crystal sphere could cut a ship in half.

A crystal shell was in no way weakened by this temporary magic portal; in fact, if any objects happened to be touching the area of effect, such objects would remain where they were. Multiple vessels could easily follow a first through a created portal.

Components
Create portal required verbal and somatic components and a wire wrapped around a piece of amber. In the elven spellcasting tradition, the verbal component was "Ilesté al tiveniel no aluviath béthude menoa tiré aláo galatrivé".
