Hell it is me, with some big news! Patch 1.9.7.13 launches TODAY, and let me tell you: this is one tasty update packed with new features, balance changes, and quality of life improvements - including some that folks have been asking about for a LONG time.
Ever been hesitant to grab an item or activate that card because you can’t quite remember what it does, exactly? Well no longer – because we’ve added ITEM DESCRIPTIONS for every collectible, consumable, and trinket in the game! You might just find this handy if you happen to be one of the few people who, for some reason, has trouble keeping track of every single effect from all 1000+ of them. You’ll need to beat Mom to unlock this feature, and then collect each item at least once to unlock its description text. And then you can finally read stuff while playing a video game, like some kinda nerd or something!
Trinkets also got a big ol' load of love in this update! Alongside a few item buffs, a number of weaker trinkets have been improved to make em more useful. Plus if you’ve unlocked golden trinkets, or have played some runs with Mom’s Box, then you probably quickly realized that a lot of the so-called ‘upgraded’ trinkets kinda sorta had no upgraded effects to them at all, actually. That has been fixed with the addition of upgrade effects for EVERY trinket, including some that are pretty unique and powerful. And for many of them, if you’re lucky enough to collect a golden trinket AND Mom’s Box at the same time, you’ll unleash that trinket’s final form, a super powerful tripled effect!
We even have something extra special for all you masochists out there – there’s a new kind of deal to be found in Devil Rooms that won’t cost you permanent loss of your hard-earned heart containers. Instead, simply hurt yourself on some gnarly sacrifice spikes once or twice to get the goods! And “the goods” in this case are from a selection of Devil Room items that are perfect for hurting yourself EVEN MORE!
Plus a whole bunch of other cool stuff! Now have some patch notes:
