Dimension Jump

You must make a saving throw based on your magic type, DC 18 if unthreatened. If you are threatened (in combat), the DC is 20. 

This spell instantly transports you to another dimension. If you rolled DC +4, you can choose which destination you appear where you have been before. If you succeeded your saving throw, but are below the DC +4 threshold, you transport to another dimension at the DMs discretion. DM may choose to have you roll a d4, for example, and determine the location based on that result.
