I'm sure there were some more but my memory has lost me, as well as plenty of devil rooms with items that I'm afraid to say I don't know what they are yet haha. Brimstone Buddy (Not really necessary when playing Azazel) Seeds, essentially random strings of characters, are used as the basis for all decision making in the game.
Now I don't remember exactly what order I got these items in, so I'll just go ahead and list what I got: Second floor, item room gives $$$ = DMG (and I racked up about 70 cents by the end I believe). Grants immunity to damage from Fire Places or enemy fires, but does not heal Isaac. If Isaac has no Red Heart containers or full health, no damage is taken.
Touché! Disclaimer, still learning the items of TBOI, so excuse me if I don't know the names, but I can tell the effects they give heh. All explosions heal Isaac instead of damaging him.
