A scroll of teleportation can be used for teleporting. According to the spoiler scrl-343.txt, its cost is 100 zm and relative probability 7%. It takes between 10 and 19 charges (inclusive) for a magic marker to write one.
If the scroll is blessed, you will be asked whether you want to teleport. If the scroll is not cursed, you will teleport to a location within the same level you currently are. In case of a cursed scroll, you will be teleported to another level. If you have teleport control, you will always be asked where you want to be teleported. Otherwise, the teleport is uncontrolled and your new location will be chosen randomly.
If you read an uncursed scroll while confused, with teleport control, you can level teleport and pick the level, however, there is still a chance that the teleport may be random.
This scroll is the only scroll that will be generated in a closet, making it somewhat easier to identify.
The Amulet of Yendor has an effect on using scrolls of teleportation. If you are carrying it, there is a 1/3 chance that nothing happens and "You feel disoriented for a moment." This always happens if you attempt to levelport while carrying the Amulet. You also receive this message if you are trying to teleport on a non-teleport level, such as Sokoban.
