My first attempt, after just starting the story, I blinked into a wall where I could not roll or blink out of by stairs, first level. Second round, I got clear back to the basement with the device, and blinked…to under the floor, where I could swim under the house (map) but not get back to surface w/o “leaving the area.” A little frustrating, mesmers have to blink here to get away from all the mobs. Just passing along.
