Teleportation]

[Waldham]

Hello, I have a question about teleport spell.

Quote:

Incorrect knowledge of the location's appearance usually causes the spell to fail, but it could instead lead to teleporting to an unwanted location or some other unusual mishap determined by the GM.

Does it mean that the spellcaster must already visited the location for the destination ?

Or the knowledge of the location on a map is enough ?

Does a memory palace permit to know the destination and use teleport from this ?

Same question with eidetic potion, potion of shared memories, mnemonic acid.

Thanks for your future answer.

While they don't need to have visited the place from what I can see, After all one can reasonably assume that incorrect knowledge is due to it being second hand knowledge, Or that the landscape has changed significantly. They still need to know the position,distance and direction they want to travel, and at minimum identifying landmarks of said location. A map will help if it is precise enough and includes identifying features such as landmarks or landscape, as will any other means of information sharing.

Just going off my own experience with maps in general, you absolutely need a map local to the area you want to go, Like a town/city map or one that shows off the landscape.

For larger distances they also need a larger map that shows both your location and the location you want to go to, Like a regional map or atleast some very detailed instructions on where this place is.

If a wizard is familiar with the region and knows teleport then its also reasonable that they have memorized city locations and are able to point them out on an unmarked map, even cities they have never been to.

It's pretty much deliberately left vague so the GM gets to decide how likely it is to fail and how potentially dangerous it is. Teleport (even after making scry and fry very difficult) can have a massive effect on campaigns so they want the GM to decide how it works in their campaign,

So, only your GM knows for sure.
