I don't have any players in my campaign high enough yet to worry about that. I hadn't seen that before. We had initially stated at the beginning spell components are not consumed. I'll need to amend that to say unless the spell says otherwise. Hehe. That makes a teleportation circle very expensive and impractical. One of the things I saw to spend money on is to commission a fortification to be built. even a basic fortification costs 10,000 to 50,000 gold. To put a permanent circle in it costs nearly as much as the fortification itself plus a year of time. Something when / if the characters get to that point I'd have to consider options.
