Which class ? In case ogre kills you each time you run in the alley, I can give you some tips from my own experience.

-try to go for the middle first. The noise of the smashing ball will bait ogres.then sides should be fine for short time but enough to deposit the others 2.

• you should always have your super in case an ogre spots you in case you re not confident with this part, because of the damage resistance, you should have enough time to go to hide. You dont have to rush, you can stay in a cave and wait until you have your super back. ( bring a set of armor in your inventory with full intellect, you will save 2min+)

-clear all the ads, dont rush.
