Do I pay prayer points when teleporting with the red Teleport tile, or from an obelisk, and where can I land?
Yes, normal teleport costs apply. The red Teleport tile moves a troop from an obelisk to another obelisk, never to a pyramid, for the usual 2 PP. Stargate lowers a pyramid teleport to 1 PP but does not change the destination or the DI card's cost.
