Rule clarifications for the teleportation circle spell.
Learning Sigil Sequences
If a spellcaster who already knows the teleportation circle spell (even if it is not prepared) encounters a permanent Teleportation Circle in their adventures, the caster can memorize the permanent Circle’s sigil sequence after one minute without a DC check. Success is automatic.
If a spellcaster who does not yet know the teleportation circle spell encounters a permanent Teleportation Circle, they may make an Arcana check at Medium difficulty (DC 15) to attempt to memorize the sigil sequence. If they succeed, the caster still cannot use the Teleportation Circle unless and until they learn the spell or have access to any other teleportation-type spell or device, at which point they will be able to teleport to the permanent Teleportation Circle. If they fail, they cannot attempt to memorize the sigil sequence for the same permanent Teleportation Circle until they have raised a level, increased their spellcasting ability, or learned the teleportation circle spell.
When a spellcaster first learns the teleportation circle spell, the two sigil sequences they automatically learn will be for new circles they do not already know, not ones they have previously successfully memorized. In addition, the ones they automatically learn cannot be for permanent Teleportation Circles that are protected against scrying and divination (such as with a nondetection spell). Spellcasters can still study and memorize a protected circle’s sigil sequence if they encounter it and can still teleport to it even while it is protected against scrying unless it is somehow blocked or protected by other barriers to teleportation, such as the forbiddance spell.
When a spellcaster first learns the teleportation circle spell and automatically learns the location of two permanent Circles, the player can focus their attention towards a general location (a castle, a town, an island, a continent). If possible, the DM will find an unprotected Teleportation Circle in the “general vicinity” or direction the character is looking, though this may end up being dozens of miles away, even if there are closer portals to the character’s target. The more the character knows about the target area, the closer they may get, but even so, the sigil sequence may not be exactly on target. Of course, if no permanent Teleportation Circles exist in the target area, the spellcaster may learn a sequence for one even farther away. Most small towns won’t have a permanent Teleportation Circle, for example, unless a powerful mage decided to retire there or the town was built near the ruins of an ancient temple. A spellcaster focusing on a particular town may find that the closest portal is in a big city hundreds of miles away.
Temporary Teleportation Circles
If a teleportation circle spell has been cast to create a temporary Teleportation Circle, the circle remains available until damaged or the end of the turn in which it is used, or after the caster uses it if they choose to end it as they pass through the portal. The sigil sequence will not be automatically known by anyone learning the spell for the first time, as that only conveys the sequences of permanent circles. However, if the sigil sequence is communicated to someone else (such as through telepathy or other communication spell), they may use the temporary Teleportation Circle as a destination. Once used this way, the temporary Teleportation Circle is destroyed, just as if it were used as an origination circle. For every hour that the temporary Teleportation Circle remains unused, there is a cumulative 10% chance that the chalked outlines of the circle will be damaged or faded, rendering it unusable (e.g., 10% after the first hour, 20% after the second hour, and so on until there’s a guaranteed 100% chance after the tenth hour).
Using Permanent Teleportation Circles
If a permanent Teleportation Circle is being used as the origination spot for the spell, the spell requires no material components (as the components are already embedded in the permanent circle), and only takes one Action to cast (as the full minute for drawing the circle is not required).
If a character has memorized the sigil sequence for a particular permanent Teleportation Circle but does not know any teleportation spells, they may still “guide” a teleporting group they’re accompanying safely to that circle. (For example, the rogue Alistria has successfully returned from scouting out Windsor Castle, where she found and memorized the sigil sequence of a concealed Teleportation Circle. The powerful wizard Marius can then safely cast teleport to send Alistria and her companions to that Teleportation Circle without possibility of error even if he has never personally seen it, so long as someone in the teleporting group knows the sigil sequence. She may choose to teach the sequence to Marius, or he may cast the spell in a way that allows her to determine the destination.)
