This was changed when Booster Pack 2, while not making items guaranteed as they were in Flash Isaac, made them significantly more likely, and gave them a mechanic where the player was given up to four items and could pick one of them. Not only did devil rooms have better items on average, they tended to have items more often — angel rooms from Rebirth onward have a chance to not contain an item at all, simply having a few hearts that likely won't help a player good enough at avoiding damage to get angel/devil rooms in the first place. Between Rebirth and Booster Pack 2 of Afterbirth†, angel rooms are almost entirely ignored outside of Mega Satan runs and devil rooms are preferred.In a way, this emphasizes the point of how religion at its core can be used for good, so long as it's used by those with genuinely heroic intent and actions. Isaac destroys the tainted, deranged fundamentalism that has plagued his family, himself especially, and uses the good parts of it (in this case flight, Holy Mantle, and extra health) to face off against a giant biblical monster and its Four Horsemen. Beating the Beast also counts when you think about it.Catharsis Factor: Beating Dogma, especially for people who have grown up in fundamentalist families.By then, however, you'll probably have accumulated soul hearts or even more items from past boss fights, so it's not like the challenge both bosses present really matters. Thanks to the buffs to Kamikaze (its explosive radius was increased and its damage was increased from 40 to 185), the item has gone from an item that can kill practically everything up until the Womb (or sometimes even the Depths), to a clean One-Hit Kill on everything in your path (thus allowing you to lure in even the strongest enemies and let the item rip) on top of curb-stomping most bosses, with only the fights with It Lives! and Satan being legitimately challenging. The Blue Bomber challenge became this in Repentance.Fetus bombs whenever you decide, vastly decreasing the chance of you accidentally hitting yourself with your own explosions. The Remote Detonator also allows you to explode your Dr.
Fetus, an Infinity +1 Sword that can make short work of almost every enemy in the game and also grants you infinite explosives to search for tinted rocks or Secret Rooms.
The Demo Man challenge is a breeze as you start out with Dr.The only legitimate obstacle in your way will be objects like rocks, but even then, an item that gives spectral tears eliminates this. The Computer Savvy challenge is by far the easiest in the game, as you start out with Technology, Technology 2, and Spoon Bender, meaning you fire lasers that curve themselves to hit their targets for you.There will also always be some empty rooms, and it's possible to spend quite a long time in the arcade with virtually no chance of death.
