At-will, standard action, DC 17+; you teleport yourself to a location you know well—a place you have visited at least three times and can vividly picture in your mind. The maximum distance depends on DC:
DC
Maximum Distance
17
1 mile
19
10 miles
21
100 miles
23
1,000 miles
25
Anywhere on the same plane
DC +2: bring along one willing creature you touch (stackable).
If your memory of the location is slightly off (it has been remodeled, or you only visited once), the DC increases by +2 to +4 and you may arrive slightly off-target (within 1d10 × 10 feet of intended location).
