Hidden Item Effects You Didn't Know About #4 - The Binding of Isaac Repentance

[@Iago_Dezdel]

7:20 I love the fact when you pick up tmtrainer it causes all enemies to freeze and burn. The reason this happens is due to how it worked in gen 1 pokemon. When you activated tmtrainer effect in a battle by a glitch move, the music fades, the pokemon is frozen solid and the game states that tmtrainer is frozen solid and is hurt by the burn. When that happens the Pokémon's health us drastically increased and slowly goes downs and the health is wrapped around a few times. This should always kill it.

While the Left Hand causes the chests in The Chest to contain Devil Deal items, Gilded Key will do the opposite in the Dark Room. The starting chests will contain regular items.

The broken padlock trinket also allows you to do that, just with a bomb instead of a key.

[@terrariaskeletonpre1.0.39]

not sure if this is ACTUALLY obscure or not, but in relation to piercing bombs with dr fetus... the forgotten synergises with dr fetus, which is fairly obvious, when you pick it up, the forgotten can charge his shot to instead throw a bomb instead of the bone, but did you know this bomb can actually deal contact damage? it only works when the bomb is airborne, but i thought it was an interesting little tidbit for the forgotten.

How To Jump will reset the fuse on the bomb form of Tainted Forgotten (such as in the Hot Potato challenge). Useful if you need some better timing on the explosion loop or just want to carry the skeleton without needing to constantly throw it around.

The blood bomb thing I actually learned about on accident when I walked into the Boss Rush and opened a chest that spawned from a tinted rock, thinking I could take the drops and leave. Dunno why I even went in or even cared to look at the items, the trophy was sitting in the adjacent room waiting to be picked up. I was wrong however, for the Boss Rush started and I panicked, especially because I was doing the challenge where you could only use little poop friends to hurt enemies. If it weren't for my Poop active item, a LOT of patience, and several blood bombs I would've died. Weirdest learning experience I've ever had.

For Hallowed ground it's important to mention that the poop drops not on where you are, but where the poop (familiar) is positioned, so if you have too many familiars, you need to make sure the poop (familiar) is close to the devil beggar/blood donation machine when trying to abuse it.

a not very well known synergy The Poop + Hallowed Ground Activating The Poop causes that instead of spawning a common poop, it spawns Hallowed Ground without taking damage (And the effect of spawning it by taking damage can still be used)

[@ThEjOkErIsWiLd00]

Here's a neat little obscure trick that I think should definitely be in the next video: You have the Options? item as well as the Broken Padlock trinket, a chest + another pickup you really want/need spawns after you clear a room, you can bomb open the chest (except haunted chests), grab the pickups that spawned from it and the other pickup won't disappear! It's only if you touch the opened or unopened chest that makes the other pickup disappear. However, if the bombed open chest spawns an item instead and you snag it, it WILL cause the other pickup to go poof. Oh, and you can do this with Sharp Key as well, but you'll ofc be using keys instead.

[@Mixxium]

So it's really cool to see that the suplex plus berserk combo was changed from a bug to an actual synergy. I specifically remember seeing the combo being used before but if you did it right the enemy was deleted. Really cool that it's an actual thing now.

[@acontic8203]

This is one obscure fact, maybe a bug? When playing in multiplayer as tainted Jacob and Jacob and Esau normal Jacob will be damaged by the dark Esau (other characters are unaffected) It's not about an item, I know, but I think it's pretty interesting nonetheless

[@NerdTheDemon]

I'd assume it's intentional, as it does make sense. Dark Esau goes for Jacob, because in Dark Esau's eyes it's still Jacob. It'd be a pretty huge coincidence if the one character that's affected by Dark Esau (other than Tainted Jacob) is actually just Tainted Jacob from the past, is indeed a bug.

[@ghostlyfreak]

[@bartholomewjenkins164]

Maybe this is silly to even bring up as a "lesser known" effect, but it's something I didn't know about for a long time since I never looked at the wiki - the Old Bandage gives you a chance to drop a red heart when taking damage! For a while I thought it was just the worst boss item, worse than Breakfast because it doesn't even give you a filled heart container

This makes it one of the best health ups, especially when paired with blood donation machines or blood oath.

Not related to item effects, but it's a cool little detail I noticed in game: When a maggot type boss (Chubby, C.H.A.D. or Carrion Queen) eats a bomb while charging, you can see the glow inside of the boss coming from the lit fuse of the bomb. It's very subtle, but easier to notice with Curse Of The Darkness Also probably a better known fact, but when aforementioned bosses eat a bomb, its fuse time is reset (so for example if a bomb is about to explode and gets eaten, it will still explode with a delay)
