Jaunter's Hop assumes you got Dimensional Agility feat. If so, how can this work in the middle combat? I can see this as part of an ambush or during a surprise round, but I'd like to know if you do this in the heat of combat and how to pull off what Night Crawler does in the Comics, Cartoons, & Movies.
It would be cool and thematic for sudden teleportation, as offered by either of these options, to enable sneak attack in some fashion. But unless one takes the Dimensional Savant feat, nothing about teleporting actually accomplishes that.
However, these options don’t prevent sneak attack, either. If you would trigger sneak attack against the target from where you choose to teleport too, then you still do with either of these options. So teleport into a flanking position, or next to a target denied its Dex to AC, and you will get sneak attack. Which is really the same thing as you are doing with Dimensional Savant, only you are flanking with yourself.
