By using this spell, the caster is able to enter a tree and move from inside it to inside another tree. The second tree must lie in approximately the direction desired by the spell user and must be within the range shown in the following table.
Type of Tree Range of Area of Effect Oak 600 yards Ash 540 yards Yew 480 yards Elm 420 yards Linden 360 yards deciduous 300 yards coniferous 240 yards other 180 yards The tree entered and that receiving the caster must be of the same type, must both be living, and of girth at least equal to that of the caster. Note that if the caster enters a tree, an ash, for example, and wishes to pass north as far as possible (540 yards), but the only appropriate ash in range is to the south, the caster will pass to the ash in the south. The pass plant spell functions so that the movement takes only one round. The caster can, at his option, remain within the receiving tree for a maximum of one round per level of experience. Otherwise, he can step forth immediately. Should no like tree be in range, the caster simply remains within the first tree, does not pass elsewhere, and must step forth in the appropriate number of rounds. If the occupied tree is chopped down or burned, the caster is slain if he does not exit before the process is complete.
