Be The Final Boss Beginner Guide
Codes → cheap lineup → Skill Tree → Wave 25.
By Bloxron Editorial Team · Last updated
You’re the Final Boss. Heroes keep coming; your army and Skill Tree have to keep up. First hour: codes, a cheap lineup, Wave 25.
Common mistakes
- Skipping codes, then wondering why you have no Coins
- Parking two dual-slot units before Population is up
- Dumping every Soul at the Altar before the frontline can tank
- Burning Altar rolls in Gold Rush instead of waiting for Cursed Moon
- Never sitting on the throne once it gives a combat buff
First session
- Finish the tutorial. Learn placement, the Altar, and where the Codes Board is.
- Redeem every active code. Settings → Codes. Start with betheboss, then clear the list on our codes page. Coins go to the Skill Tree; Souls sit for Altar rolls.
- Build a cheap lineup that doesn’t leak. Iron Skeleton (or Bone Grunt until you get one) up front, Skeleton Archer / Imp Bomber behind. Don’t stack two dual-slot units until Population is up.
- Spend Coins on stuff that sticks. Slot-capped? Population first. Otherwise Unit Damage or Unit Health, then Coin Income, then Boss Attack / Health. Buy a weapon after the leaks stop.
- Hit Wave 25. First checkpoint that matters. After it, look at Shiny Lava Imp / thicker tanks on the minion page before you spam more Souls.
- Play the weather. Gold Rush = farm Coins. Shard Storm = farm shards. Cursed Moon = roll the Altar. Don’t waste mutation rolls during Gold Rush.
Currencies
| Resource | Spend on | Note |
|---|---|---|
| Coins | Skill Tree, weapons, shop | Codes dump these; Gold Rush makes kills pay more |
| Souls | Altar rolls | Don’t spend these like Coins |
| Fusion Shards | Fuse / upgrade units | UPD2 bumped drops; Shard Storm helps |
| Forge Stones | UPD2 forge / craft | Check recipes in-game |
| Spin Tickets | Reward wheel | Common in codes |
| Boosters | Timed buffs (Coin / Soul / Luck / Attack / Health) | Save for checkpoint bosses |
Early Skill Tree order
Names might differ slightly in your tree UI — match the idea. Full tips on Skill Tree.
| Branch | Priority | Why |
|---|---|---|
| Population | High | Dual-slot units need the slots first |
| Unit Damage | High | Kills happen before the throne |
| Unit Health | High | Keeps the early frontline up |
| Coin Income | High | Pays for later nodes and weapons |
| Boss Attack / Health | High | You’re the backup when stuff leaks |
| Soul Harness / Harvest | Medium+ | Matters once Wave 25 farms feel real |
| Altar / Summon Luck | Medium | After you can survive long enough to roll |
| Castle / Realm / Auto | Later | QoL — not a substitute for unit stats |
Wave checkpoints
| Wave | Meaning |
|---|---|
| 25 | First real gate — dump tutorial fillers |
| 50–75 | Thicker tanks + better weapons |
| 100 | Pricey melee / support tests; lots of runs hitch here |
| 125 | Late DPS (Demon Butcher line) starts deciding clears |
Weather windows
Each weather lasts about five minutes, then roughly ten minutes of nothing. Watch the HUD timer (usually bottom-right). More farm notes on Events.
| Event | Effect | Do this |
|---|---|---|
| Gold Rush | Kill Coins ×1.75 | Fight hard, bank Coins |
| Shard Storm | Shard drop ×1.3 + extra roll | Keep killing for Fusion Shards |
| Cursed Moon | Mutation chance ×2 | Park at the Altar and roll |

FAQ
What’s the real first goal?
Codes in, frontline stable, Wave 25 clear. Fancy rolls can wait.
Buy a weapon early?
Only after you stop leaking. Population and Unit Damage pay more first.
When do I roll the Altar?
When the line can hold — ideally under Cursed Moon. One unit that plugs a hole beats five random gambles.
Can I mix Coin and Soul spending?
Coins = permanence. Souls = army. Keep the piles separate.
Armor / Battlepass?
UPD2 stuff. Armor helps once leaks are your problem; Battlepass is optional.
