The plant door spell opens a magical portal or passageway through trees, undergrowth, thickets, or any similar growth—even growth of a magical nature. The plant door is open to the caster who cast the spell, casters of a higher level, or dryads; others must be shown the location of the door. The door even enables the caster to enter a solid tree trunk and remain hidden there until the spell ends. The spell also enables the passage or hiding of any man-sized or smaller creature; hiding is subject to space considerations. If the tree is cut down or burned, those within must leave before the tree falls or is consumed, or else they are killed also. The duration of the spell is one turn per level of experience of the caster. If the caster opts to stay within an oak, the spell lasts nine times longer than normal; if within an ash tree, it lasts three times longer. The path created by the spell is up to 4 feet wide, 8 feet high, and 12 feet long per level of experience of the caster. This spell does not function on plant-based monsters (shambling mounds, molds, slimes, treants, etc.).
The material components for this spell are a piece of charcoal and the caster's holy symbol.
