Hey everyone, Guigz here. A lot of you had already spotted that something was going on under the hood for a while, sharp eyes. We were running a test of the new progression system, and honestly it was a bit of a rough ride at times. The Ice Blaster doing absolutely unhinged damage? Yeah. That was us. Sorry. (And a few other units too, but let’s not dwell on it 😅)
Today we’re properly launching the system the way it was always meant to work, with all the pieces in the right place. This is what we intended from the start, a progression system that actually feels good to play, top to bottom.
It’s the biggest change we’ve ever made to progression in Castle Busters, and we want you to have the full picture before it goes live. Here’s everything.
Our goals with these changes
- Make every level you earn feel powerful
- Make every unit, Common or Legendary, worth collecting and playing
- Keep your castle and your army growing together for fairer battles
- Make sure everything you’ve already earned comes right along with you
This is a gradual rollout
Not everyone will see these changes at the same time, we’re rolling this out progressively to existing players. And if you’re wondering whether you can still battle friends or other players on a different version, the answer is yes. Levels adapt proportionally between both versions, so matchups stay fair no matter where each player is in the rollout.
1. Fewer Levels, Bigger Upgrades
Max unit level is moving from 100 to 50, and every level now gives the same meaningful jump in power. Right now your earliest upgrades hit hard and later ones feel smaller. On the new scale, every level lands with the same punch, all the way to 50. An upgrade always feels like an upgrade.
Do you lose levels? No.
Your levels are simply halved onto the new scale, and your power stays exactly where it is today. A maxed unit stays maxed. Same strength, tidier number.
| Old level | New level |
|---|---|
| 100 (max) | 50 (max) |
| 80 | 40 |
| 50 | 25 |
| 24 | 12 |
| 10 | 5 |
2. Rarity Tiers, Freshly Polished
Every unit now has a rarity, Common, Rare, Epic, or Legendary, each with its own look. Rarer units also start higher on the new scale, so your best finds show up ready to fight.
| Rarity | Starting level |
|---|---|
| Common | 1 |
| Rare | 5 |
| Epic | 10 |
| Legendary | 25 |
Your unit cards come with you
Your cards are being rescaled to match the new upgrade costs. This is not a nerf. Upgrade costs now scale with rarity, the rarer a unit, the fewer copies it takes to level up. Your existing cards move by exactly the same amount, so your progress toward every unit lands precisely where it was.
| Rarity | What happens to your cards |
|---|---|
| Common | x2 |
| Rare | ÷ 1.8 |
| Epic | ÷ 16.5 |
| Legendary | ÷ 200 |
Your Wild Cards become four
Your Wild Cards split into Common, Rare, Epic, and Legendary automatically at login. Everyone is guaranteed at least one of every rarity.
| Wild Card type | Share of your current Wild Cards |
|---|---|
| Common | 77% |
| Rare | 20% |
| Epic | 2% |
| Legendary | 1% |
Every chest’s drop rates, out in the open
You’ll be able to see exactly what each chest can drop, right in the game. No more guessing.
| Reward | Bronze | Silver | Gold | Platinum | Diamond | Magical |
|---|---|---|---|---|---|---|
| Common Cards | 69.50% | 64.80% | 49.60% | 32.55% | 38.00% | 34.30% |
| Rare Cards | 30.00% | 30.00% | 35.00% | 40.00% | 25.00% | 35.00% |
| Epic Cards | 0.50% | 5.00% | 12.00% | 13.00% | 14.00% | 15.00% |
| Legendary Cards | 0.00% | 0.00% | 3.00% | 5.00% | 7.00% | 5.00% |
| Common Wild Cards | 0.00% | 0.00% | 0.00% | 5.00% | 8.00% | 5.00% |
| Rare Wild Cards | 0.00% | 0.00% | 0.00% | 3.00% | 5.00% | 3.00% |
| Epic Wild Cards | 0.00% | 0.00% | 0.00% | 1.00% | 2.00% | 2.00% |
| Legendary Wild Cards | 0.00% | 0.20% | 0.40% | 0.45% | 1.00% | 0.70% |
Worried a Legendary will take forever to level?
It won’t. We’ve matched how you earn and upgrade each tier to how often it drops, so every rarity climbs at a rewarding pace. Rarer means special, not slower. Collect boldly and play with whatever you love.
3. Castle Levels Enter the Fight
Your Castle Level sets how many blocks you can build and how high you can upgrade your materials. It rises as you hit milestones on your Forge Pass, the same track that powers up your deck. That means your castle and your army grow together, which makes for fairer, more evenly matched battles as you climb.
4. Forge Pass, Rebalanced
Rewards further along the Forge Pass now need fewer Stars to unlock. Same rewards, shorter climb. And you keep your place, you’ll stay at exactly the Forge Level you’re on today.
5. A Thank-You Gift
Everything you’ve earned carries over automatically, your levels, cards, Wild Cards, castle, and Forge Pass. You don’t need to lift a finger. And there’s a gift waiting the first time you log in.
Up to 500
Gems (from Mailbox)
Up to 60,000
Coins (First login)
6. A Few Balance Tweaks
Some reward tracks retuned
Daily-win rewards, chain offers, and arena rewards have been retuned to line up with the new economy.
Mid-tier castle wood costs
Mid-tier castle wood costs are going up slightly to stay balanced with the new system.
Bomber
Bomber’s castle damage is being tuned by 10% to keep battles fair as the new economy settles in.
This is the biggest thing we’ve built for Castle Busters yet. We’re building this game together, and we can’t wait to see what you think. Tell us on our socials and in the community, we read it all.
See you on the battlefield. 🏰
