Stuck in Festering Sewers

Playing a Paladin in Festering Sewers map on echo, used Smite near chest, destroyed objects which teleported me behind chest. No mobs remaining to use same tactic to get out and nothing works to free me. Have to exit level to get out, thus failing the echo.
Yes, I know the screenshot doesn’t show me having Smite skill but that’s what I changed around to try another skill to get out. Tried Shield Bash, Shield Rush, Warpath, nothing works.

I’m surprised shield rush didn’t work.

Yeah, I figured that would get me out of it but it didn’t do anything, wouldn’t even activate in that spot.
