Create Major Helm

By casting this spell, the spellcaster can transform a normal chair or seat into a major spelljammer helm suitable for powering a ship through space. This does not replace the need for a permanent magical helm on board, and is used primarily in emergency situations.

The major helm can power a ship up to 100 tons. In operation a major helm is identical to regular, permanent spelljamming helm, with one exception. If a helm created by this spell is successfully dispelled, it will disappear and must be created anew.

A ship powered by this spell travels at a speed based on the type of ship (using the ship's stat block) within the phlogiston, a crystal sphere, or in the sky or ocean of a planet and 100 million miles per day when at spelljamming speed while in the phlogiston.

This spell's duration increases by an additional 7 days when you reach 11th level, and 17th level.
