Unlock[]
The achievement to unlock Schoolbag has something to do with entering shops, got it on my 2nd run with BP5 when walking into one. -Frionil (talk) 10:28, 1 May 2018 (UTC)
I think to unlock this you need to enter on all shops from basement 1 to dephs 2. --JuniorDarkness (talk) 01:37, 2 May 2018 (UTC)
Just attempted this on a new save, can confirm this is how you unlock the item --Kottenchilly (talk) 03:36, 2 May 2018 (UTC)
I failed to unlock the item when I had a Depths XL floor with only a single shop after making sure to visit all of the previous shops. --Anyxbody (talk) 08:00, 6 May 2018 (UTC)
Backpack redirect[]
Idk how to add it but typing in "backpack" should redirect to this page, in the wiki's current state if you type it in it's just completely blank, I had to google "Isaac backpack" to figure out it's called schoolbag
