Everything

Used mostly to shorten distances during travel, a “warp-gate” feat opens a small hole in space and lets the mage pass through. Generally, a warp-gate lasts a turn or two – long enough to enter – and then closes up again.

Depending on the size of the warp-gate, this might be a Correspondence 3 or 4 Effect. Given the temporary nature of such gates, a mage’s player generally needs to roll only the number of successes noted on the Teleportation Locations chart in order to establish that gate. A warp-gate that gets you back home? Two successes. One that gets you to a place you saw on the Internet? Five successes… and by all the gods, don’t botch!

For obvious reasons, it’s a good idea to use the Spotting a New Location feat before opening this sort of passageway.
