Be The Final Boss Skill Tree
Where Coins go first — Population, Unit Damage / Health, income, Boss upgrades, then Forge Stones into matching Armor sets.
By Bloxron Editorial Team · Last updated
Coins buy permanent nodes. Population unlocks dual-slot units; Damage / Health keep the line alive; Boss stats clean leaks. Match the branch idea if your UI names differ.
Early priority
First Coin dumps that unlock dual-slot units and stop early leaks.
| 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 |
If you’re stuck
Buy for the wipe you just took.
| Symptom | Buy | Why |
|---|---|---|
| Good unit stuck in inventory | Population | Dual-slot Imp Bomber / Bone Guard / Warlock lines need slots first |
| Normal waves leak to the throne | Unit Damage or Unit Health | Army should clear before you become the carry |
| Only bosses wipe you | Boss Attack / Health + weapon | You’re the cleanup — tree alone won’t fix a soft sword |
| Broke every run, slow Coin flow | Coin Income | Pays for every later node |
| Can hold Wave 25, rolls feel trash | Soul Harness, then Summon Luck | Soul income first; luck after you survive long enough to roll |
Later spend
- Castle / Realm / Auto are QoL — they don’t replace a soft frontline.
- After Wave 25, split Coins between tree nodes and one weapon (Gilded Longsword is the usual early pick).
- Forge Stones go into Armor once leaks are rare — finish a matching three-piece set so passives stack.
- Altar Luck ≠ mutation luck. Mutation odds live on weather / the Double Mutation pass.
Armor (Update 2+)
Forge Stones and Battle Pass gear for the boss — not minion slots. Live costs and passives are in the Armor menu.
- Helm leans damage, body leans HP, guard splits both — matching sets stack the same passive three times.
- Most sets craft with Forge Stones. Hellfire Mantle / Obsidian Plate track the Battle Pass; Juggernaut is a Robux full-set buy.
- Void Knight body is the big Forge sink — don’t start Secret crafts until Amethyst / Emerald already cover the holes.
| Set | Role | Note |
|---|---|---|
| Amethyst Gladiator / Emerald Mantle | Mid save | Cheaper Forge Stone sets while you bank for Secret gear |
| Void Knight | Long-term Forge goal | Best overall set across helm / body / guard — Void Drain lifesteal on each piece |
| Hellfire Mantle | Battle Pass melee | Nova on combo hits — chase if you already own the pass and fight in melee |
| Royal Paladin | Safe clutch | Last Stand heals — strong if runs die at low HP more than they die to DPS gaps |
| Golden Bastion | Farm swap | Coin passive for long AFK clears — swap off before hard pushes |
FAQ
What should I buy first?
Population if dual-slot units are locking you out. Otherwise Unit Damage or Unit Health, then Coin Income, then Boss Attack / Health.
Does Altar Luck raise mutations?
No — Altar / Summon Luck helps rarity. Mutation chance is Cursed Moon or the Double Mutation gamepass.
Skill Tree or Altar with my first Coins?
Coins → Skill Tree / weapons. Souls → Altar.
When do I spend Forge Stones on Armor?
After Wave 25 leaks are rare and you’ve bought early tree + one weapon. Build Amethyst Gladiator or Emerald Mantle first, then commit Forge Stones to a full Void Knight set (or Hellfire Mantle if you own the Battle Pass and fight melee).
Mix armor sets or finish one?
Finish one matching helm + body + guard. Passives stack per piece — three Void Drain procs beat a random mix of higher rarity labels.
