First steps when you load in
StepIn short
Redeeming codes and opening card packs before anything else puts you ahead from the very first minute.
The moment you join, head straight to the code entry field and redeem any active codes — they hand out free gold and roll packs, and they expire, so waiting costs you. Once you have packs, open them to build up your card collection. After that, you are ready to take on your first bosses.
- Redeem codes find the code entry field in-game and enter every active code you have to collect free gold and roll packs.
- Open your roll packs each pack gives you random cards across nine rarities, so open them right away to see what you are working with.
- Challenge a boss with cards in hand, jump into one of the 18 worlds and take on a boss to earn your first drops.
- Check the Boss Tower the tower lets you fight bosses in stages, so start climbing it early for additional rewards.

Traits and the Corruption modifier
Summary
Every card carries traits — bonus effects that change how it performs in battle. You can reroll those traits to get different ones, and occasionally a reroll produces a Corruption variant, which carries a larger boost than a standard trait.
- Traits bonus effects attached to each card that alter its performance in combat.
- Rerolling a mechanic that replaces a card's current trait with a new random one.
- Corruption a special outcome from rerolling that adds a significantly stronger boost than a normal trait.
06
Storm bosses and live weather events
Step
In short
Live weather events are the only way to get exclusive limited cards, so drop everything and join when one starts.
Nine different live weather events can occur in the game, each one triggering a storm boss. These bosses drop exclusive cards that cannot be obtained any other way, and only a small number of those cards will ever exist. That scarcity also makes them valuable in trades and auctions.
- Watch for a weather event when a live weather event starts in-game, join it.
- Engage the storm boss fight and defeat the storm boss that spawns during the event to have a chance at the exclusive drop.
- Use or trade the limited card exclusive cards strengthen your deck directly, or you can take them to the auction and trade system where they carry significant value.

Free-to-play habits that stack up
Check
In short
Combining codes, AFK rewards, day bonuses, and a guild gives you a steady income of cards and gold without spending anything.
The game has several systems that work together to reward players who are not spending Robux.
- Redeem new codes as soon as they appear codes give free gold, roll packs, and potions, and they stop working once they expire or run out of uses.
- Turn on auto-rejoin before you go AFK this keeps your playtime reward timer running even while you are away from the keyboard.
- Join a guild guilds let you take on boss raids with other players and enter Guild Wars.
- Hatch pets, fuse cards, and make Genie wishes these all provide additional ways to grow your collection.

Account safety
Warn
Worth watching out for
Never share your password with anyone, regardless of what they offer in return.
Do not use cheat tools
they violate Roblox's rules and will get your account banned.
Most codes can only be redeemed once per account, so a code someone else has already used will not work for you.

Common questions
FAQWhere do I enter codes?
There is a code entry field inside the game itself. Type a valid code there and the rewards — gold, roll packs, or potions — are added to your account immediately. Codes expire or get used up, so enter them as soon as you find them.
How do I get exclusive limited cards?
Exclusive cards only drop from storm bosses, which appear during live weather events. When a weather event triggers in-game, join it and defeat the storm boss to have a chance at the drop. Only a small number of these cards will ever exist, so they are rare in circulation.
What does joining a guild actually give me?
Being in a guild lets you join boss raids with other players. You can also participate in Guild Wars, which adds another source of rewards on top of your regular play.
