Rift Surge is used to debuff enemies inside the Rift, which means it can only be used if you used Banish, Cataclysm and Rift Surge's banish beforehand. It simply won't work if nothing is in the Rift and the enemies also have to be in Rift Surge's range (25 meters from you at max ability rank).

Once you "surged" rift-bound enemies with the void lightning, you can do two things: kill them or unbanish them.

1. Killing them makes the lightning jump to nearby enemies outside the rift, so you can save energy and not have to recast Rift Surge on those enemies later on if you decide to bring them into the rift.

2. Unbanishing them lets you keep those surged enemies in the rift while bringing in nearby enemies from outside, so you yourself don't have to Rift Walk out to the material plane to use Banish on new enemies. But, this causes the lightning to stop, meaning you need to recast Rift Surge to charge the old and new enemies up.

As you can imagine, combining these options from Rift Surge with Banish and Catalcysm gives you the ability to stay safe in the Rift while bringing in enemies from outside (Banish used to allow this, but it was 1 target only, now you can deal with crowds). Since Stasis stops everything from moving or attacking, you can buy yourself lots of time to figure out how to deal with your new toys (enemies) in your personal playground (the Rift). Hope this helps.
