A few questions about this spell…
Teleportation Trap:
Teleport trap wards an area, redirecting all teleportation into or out of the area to a specific point within the area determined by you at the time of casting. The destination must be an open space on a solid surface. The spell’s area overlaps walls and other solid and liquid objects (preventing intruders from bypassing the ward by teleporting into a wall or through similar means). A teleporting creature that is affected by a teleport trap can resist the effect with a Will save—if the save is successful, the creature simply doesn’t teleport at all (but the use of the teleport effect is still consumed)—either to the intended location or the teleport trap’s actual destination. A DC 27 Knowledge (arcana) allows such a creature to recognize the teleport trap’s presence, but does not reveal the trap’s linked destination.
At your discretion, the teleport trap can exclude a category of creatures, such as an alignment, a type of creature, or creatures that carry a specific item or know a password (though this only works if the creature is teleporting out of the area, not into it). You select this option and the conditions at the time you cast the spell. Overly complicated conditions may cause the spell to fail entirely. Multiple castings of teleport trap can be linked to cover a larger area, allowing teleported creatures to be directed to a single point within the combined area of the spells.
Teleport trap can be made permanent at the cost of 7,000 gp. A single permanency spell can be used on all teleport traps that share a linked destination, but the gold piece cost must be paid for each individual spell.
The Pathfinders of the Grand Lodge make use of permanent teleport traps in several key locations, trapping would-be intruders in a small wing of jail cells. At least one crypt of the Whispering Tyrant makes use of the spell as well, trapping grave robbers in coffin-sized stone cysts, there to die a slow and agonizing death from thirst and starvation.
The first question, I think I know the answer to… but does this apply to all Conjuration (Teleportation) spells? Or, is it only Teleport/Greater Teleport? I figure it works with anything that remotely feels like teleportation, whether it is Teleport, Plane Shift, Dimension Door, Jester’s Jaunt, etc etc.
Second question, it says that it redirects the teleportation. But what happens if the range of the teleportation effect isn’t powerful enough to travel the full distance? Say, you try to teleport someone with Jester’s Jaunt, it has a max range of 30ft… do they go 30ft towards the trap's designated location… or does it both redirect and enhance the teleportation effect to make them go the full distance well past the normal 30ft range to the designated location?
Last question, it says it redirects teleportation ‘into and out of’, but does it redirect teleportation ‘within’? If someone dimension doors from point A inside the trap, to point B also inside the trap, does it get redirected? It isn’t teleporting ‘into or out of’ but ‘within’ the area, so I’m unsure.
Thanks in advance for any input you might have!
