Earning achievements
Your progress is kept in your saved data, so a count builds up over all your runs, not only the one you’re in. Nothing you do in the tutorial counts. Kills add up this way toward the five kill achievements.
In co-op, most achievements count for the player who did the thing, on their own game: what your partner does adds to their progress, not yours. The game credits some to a particular player wherever they happen, like a kill from throwing an enemy onto a spike plate, which goes to whoever threw it. A trip or a squeeze with the chain counts for both of you. Stampede counts for everyone in the fight, whoever got Barca trampled.
Outfit rewards
12 of the achievements also unlock an outfit, which every beast can then wear. The Cosmetics section has them all, and the Reward column of the achievements list shows which outfit each one gives.
The Codex
The Codex keeps what you’ve met and done across all your runs. It has a screen each for your beasts, opponents, afflictions, skills, items and purchases, one for your triumphs, and one for the histories of your runs. Discover all of it and open the Codex to earn Scholarly. All of it means every beast at its top level, every skill, every affliction at each of its levels, every opponent, every item and every purchase.
