His 6th lvl Class ability apparently adds 10 ft to any teleport he does, and the Defensive Step is normally 10 ft, so he can teleport 20 ft with his Defensive Step. Just enough to get him to the bottom of the ramp.
I really can’t wait to see what they change in the next version. It’s no longer a “Mystic”, and is going back to being a “Psion”, and they’re making it much more focused on one thing or another, instead of being this jack of all trades. So Primus will likely be nerfed if/when that happens, but since he’s kind of my playtest character, I don’t mind so much. No clue when that will be released, but still.
