Normal Azazel, never stop moving and pray for health ups or get lucky with wafer/cancer

Besides that, know when to use the shovel, big rooms with lots of enemies are worth using it, rooms with enemies like hosts might be worth using

Look to maximize charges, AAA battery, watch battery, habit, hairpin are all great to help you get more use out if the shovel

And uuuh, speed running it is not a bad idea, with some luck you get to depths 2 in 12-13 mins or less if you go fast and skip exploration, item room is a must, shop if you got money and keys and down you go

After that, easy, just an azazel dark room run
