Any character but: Lost Keeper

Items: Glowing Hourglass Habit 9 Volt

Description: Whenever you take damage, you have to go back with your GH, doesn't matter how, when or what hit you, you have to go back, every time. BD Machines and Demon Beggars count as damage, Sacrifice rooms are infinite loops between going back and taking damage. Actives aren't allowed unless you have schoolbag, if you do, you can take one, but you need to have the GH in your hand all the time (except when you use the other active), passives are allowed except from the excluded ones, but however, items with the "when hurt" condition are useless, such as My Life Savings and Curse Of The Tower.

Exclusions: Items: Taurus Holy Mantle Blanket Cursed Eye Empty Vessel Infamy Conehead Metal Plate Any orbital that blocks tears Trinity Shield Missing no (if You take this one use the GH)

If you get one by accident with the "Curse Of The Blind", remove it with the console and give yourself a Breakfast, 'cause we all love some Breakfast

Trinkets: Wooden cross Butter Cursed skull Broken remote

Objective: You win if you defeat one of the followings (at least): Hush Blue Baby The Lamb Mega Santa Delirium
