Beginner Guide: First Session
A step-by-step first session: core loop, first weapon, first rolls, wave checkpoints, and the skill tree picks that matter early.
New Units & Update Changes
The latest update shown in-game: six new units, raid-exclusive secrets, four boss abilities, billion-coin weapons, and the skill nodes worth ignoring.
Castle System & Raids
Castle slot upgrades, the Imperial Knight raid join window, damage milestone rewards, and what Phase 2 changes — from 2026 raid footage.

Which Secret-rarity units exist, how rolling at the Summon Altar plays out, and what one creator’s Demonic Skull King did for his waves.
Troop Guide: What to Buy and What to Skip
A wave-373 player’s per-class walkthrough — which guards and ranged troops are worth souls, which supports and melees to skip, and how to formation them.
Castle skins walkthrough
Where the paintbrush menu is, how the four castle skin sections work, what a set costs, and whether skins are worth paying for.
How to Get Units: Summon Altar, Souls, Auto Roll
Where units actually come from — the altar's Roll button, Auto Roll stop settings, population slots, and one account's real roll totals.
Enemies Walkthrough: Hero Waves, Boss Cycle, HP Scaling
Which heroes storm your castle, which checkpoint wave each of the four bosses lands on, and the enemy HP numbers actually read off the nameplates.
Weapons Guide: Where to Buy and What They Cost

The full Be The Final Boss summoning loop: the altar and Goblin Rolly, Auto Roll stop targets, the UNITS roster, Fusion Shard conversion and roster sorting.
Checkpoints: which waves gate them, who guards them, where you restart
Every 25 waves a checkpoint gate ends in a boss. Wave 25 is Crusader Champion, wave 50 Grand Inquisitor, and clearing one makes your next run start on the wave after it.
Unit upgrades: what each star costs in Fusion Shards
The UPGRADE window names the shard type and the count per unit, and the FUSION panel converts shards upward one rung at a time — 5 into 1 at the lower rarities, 4 into 1 at Legendary and Mythic. Every figure read off frame.
Robux shop: pack prices, pass effects and the rows that flip to Owned
The in-game SHOP read off one 19-minute recording: Advanced Pack at R$ 299 with Limit 1, VIP at R$ 249, the auto-swing pass at R$ 160 — and R$ 199 later on the very same card.

Blood Spirits and the Bloodmoon Boss
The +10 Blood Spirits line the game prints after a Bloodmoon Boss dies, the run state it lands in, and the drop-rate and shop questions the footage never answers.
Armor Forge and Forge Stones
How the ARMOR FORGE tab opens, what the Helm grid and the piece card show, and how the Forge Stone counter reads — with the costs the footage never displays left unknown.
Core Objective: Defend the Castle
Be The Final Boss asks you to summon minions and defend your castle against waves of heroes. The official description establishes this loop, but does not publish wave counts, enemy stats, or recommended layouts.
- Summon minions to form a defending force.
- Protect the castle against incoming hero waves.
- Use the current in-game interface for wave-specific details.
Opening Route: Survive First, Snowball Later
A player-facing opening sequence, not an official formula. Each step should be tested in your next run rather than copied blindly: build a frontline that keeps heroes off the castle, concentrate Coins into permanent power instead of spreading them thin, and record which hero type breaks through so you can adjust unit roles and skill routes.
- Step 1 — Raise a frontline: deploy durable units so heroes cannot rush the castle directly.
- Step 2 — Spend Coins on permanent power: focus skill tree nodes and your main weapon instead of spreading resources.
- Step 3 — Log the breach: note which hero type breaks through, then adjust unit roles and skill routes for the next run.
Post-Run Diagnosis: Read the Defeat Before the Boss Name
When a run fails, identify the first failure point instead of buying upgrades at random. Four common patterns: the frontline melts before the boss (test HP and durable units first, not more damage), usable units sit in the inventory (test Population slots), the line holds but the boss wave outlasts you (compare Unit Damage, unit levels, and weapon investment), or your own boss deals too little (test weapons and Boss Attack from a safe position).
- Frontline melts first → test HP, durable units, or early wave-clear before stacking damage.
- Units stuck in inventory → invest in Population and check whether the extra slots raise your best wave.
- Line holds but damage lacks → compare the single-run impact of Unit Damage, unit levels, and weapon upgrades.
- Your boss contributes too little → test weapons or Boss Attack from a safe position without sacrificing the frontline.
Skill Tree and Weapons
The official listing says that progressing through the skill tree unlocks weapons. It does not identify individual nodes, weapon names, costs, or unlock order, so check the in-game tree before committing resources.
- Advance the skill tree to unlock weapons.
- Treat the in-game tree as the source for current requirements.
- Avoid relying on unverified build paths or cost tables.
Official Release Code
The official release code is betheboss, but the official description does not state its reward and public reports conflict. Redeem it via the Gear icon (top-left) → scroll to the bottom → Enter Code Here box → Redeem, then use the in-game toast as the reward record; codes are case sensitive. Reported active codes and source notes are listed on the Codes page.
- Enter betheboss exactly as shown, then verify its reward in the in-game toast.
- Codes are redeemed in Settings via the Gear icon at the top-left.
- See the Codes page for every active code and its source note.
What Update 1 Confirmed
Update 1 added three units, the Demonic mutation, Gold Rush, Shard Storm, Cursed Moon, and the Unit Index. The announcement does not name the three units or document event rewards, mutation effects, or Unit Index fields.
- Three units were added, without official names in the supplied source.
- Demonic mutation and three named events were introduced.
- The Unit Index was added as a reference feature.
Guides FAQ
What is the fastest way to get Coins?
Front spawn-kill placement clears waves faster than back-line formations. See the Get Coins Fast guide for screenshots and the AFK Farm Setup guide for the full layout.
What is the best AFK setup?
Stack melee and ranged minions at the enemy spawn entrance, enable Auto Roll, and sit on the throne for Throne Power income. The AFK Farm Setup guide walks through each step with screenshots.
How do I roll Demonic mutations?
Save Souls for Cursed Moon when mutation odds double, then batch rolls at the Summon Altar. The Mutations Roll guide explains Shiny vs Cursed vs Demonic and when to spend.
What units should I invest in first?
Mighty Orc is the safest long-term pick. See the Best Units & Team guide and the Tier List for ranked options with observed stats.
