What are codes used for?

Most Slayers Unleashed codes are used to get different kinds of rerolls. These include Race, Breathing, Clan, Demon Art, and more. Some offer in-game boosts like XP Boosts and Drop Boosts.

Players spawn as Humans and they can complete quests to become a Demon Slayer and unlock Breathing Techniques. You can also choose to reroll for the Demon race and unlock Blood Demon Arts. If you’re lucky, you can get the Hybrid race which can use both Breathing Techniques and Blood Demon Arts.

The Breathing and Blood Demon Art reroll codes will determine the type of abilities and attacks you can use – like Water Breathing, Insect Breathing, Akaza, Temari, and more. Experimenting with these is ideal until you find one that best suits your playstyle.

Rerolling your clan will provide you with bonuses or passive buffs that give you an advantage right from the start. You can check out the full list of clans and their bonuses to give you a better idea of how they work.

Boosts will simply give you more XP or better drops for completing quests and defeating bosses. This will be handy in acquiring new tools and reducing the grind time.
