Unlocking the Applied Esoterica badge in Peak isn't exactly easy. You'll need a specific item to spawn in your run, not to mention requiring you to actually find the item on your adventure, which is often easier said than done. Luckily, it's not locked to a biome, so given you're making good progress, your chances of tracking it down are slightly higher, but there's no way to guarantee when or where it'll pop up.
You'll also only be able to unlock this badge by playing with someone else, as the item requires at least two players to make the most of. In fact, I'm not sure it'll even spawn if you're climbing solo. So once you've invited a friend and embarked on your expedition, here's how you can unlock the Applied Esoterica badge.
