Understanding Be The Final Boss Minion Upgrade Costs
Managing your army efficiently is the core mechanic of defending your castle in Be The Final Boss. While your main boss character deals direct damage using unlockable weapons, your summoned minions act as the primary defensive line. To survive increasingly difficult hero waves, you must invest Souls into your units to scale their health, damage, and overall battlefield presence.
The be the final boss minion upgrade costs scale higher with each tier level. Spending your resources blindly on early-game starter units will leave you vulnerable during late-game waves. Instead, you must understand how these costs scale and balance your investments between the player's Skill Tree and your active minion army.
| Minion Tier | Upgrade Cost Level | Stat Scaling | Primary Role |
|---|---|---|---|
| S-Tier | Very High | Excellent | Late-wave carry, massive damage, high survival |
| A-Tier | High | Great | Reliable frontline tanking, crowd control |
| B-Tier | Medium | Moderate | Protected backline damage, support casters |
| C-Tier | Low | Low | Cheap early-wave fodder, temporary defense |
Never max out C-Tier starter minions. The Soul investment required for their higher levels is better saved for unlocking and upgrading A-Tier and S-Tier units.
Minion Tier List and Investment Value
Before spending your hard-earned Souls, you should know which minions offer the best return on investment. Below is a detailed breakdown of the current minion archetypes, their combat strengths, and how you should prioritize their upgrades.
S-Tier: Core Late-Wave Picks
- Highest Soul Priority: These advanced units scale exceptionally well.
- High Durability: Survives heavy damage from late-game hero waves.
- Top Damage: Essential for clearing elite enemies quickly.
A-Tier: Frontline Defenders
- High Health Pools: Designed to intercept fast heroes.
- Crowd Control: Keeps enemies grouped up for your boss weapons.
- Moderate Cost: Highly efficient upgrade-to-performance ratio.
B-Tier: Backline Damage
- Ranged Attacks: Deals consistent DPS from behind the frontline.
- Low Health: Vulnerable to fast-moving or teleporting heroes.
- Support Priority: Upgrade only after your frontline is fully stabilized.
C-Tier: Starter Summons
- Low Cost: Extremely cheap to summon during the first few waves.
- Poor Scaling: Easily wiped out in mid-to-late game progression.
- Replace Early: Do not spend valuable Souls upgrading these past level 2.
| Minion Group | Target Level | Soul Cost Tier | Priority | Best Use Case |
|---|---|---|---|---|
| Tanks | Max | High | Critical | Position at choke points to absorb initial hero charges |
| Melee DPS | Medium | Medium | Moderate | Flank heroes while they are focused on your tanks |
| Ranged DPS | Medium | Medium | Moderate | Place behind walls or near the castle core for safe DPS |
| Support | Low | Low | Low | Use sparingly to buff your primary damage dealers |
Do not neglect your frontline. If your tanks die too quickly, your ranged damage dealers will be wiped out instantly, exposing your castle to direct damage.
Step-by-Step Minion Upgrade Path
To optimize your resource allocation, follow this progression path. This ensures you always have enough defensive power to clear the next wave without running out of Souls.
Redeem Active Codes
Start by redeeming the launch code betheboss in the Settings menu to claim 500 Coins. Use these Coins on your early Skill Tree to boost player power.
Establish a Basic Frontline
Summon a small group of melee minions. Keep them at low upgrade levels while you farm the initial waves for Souls.
Unlock A-Tier Defenders
As soon as you collect enough Souls, unlock your first durable frontline defender. Shift your upgrade focus entirely to this unit.
Add Backline Support
Once your frontline can survive a full wave without dying, summon ranged or caster minions behind them to speed up your clear times.
Transition to S-Tier Units
In the late game, replace your starter units with S-Tier minions. Maximize their upgrade levels to survive endless scaling waves.
Following this step-by-step path prevents you from wasting Souls on weak units, ensuring a smooth transition into the late-game endless modes.
Coins vs. Souls: Resource Management
Be The Final Boss features a dual-currency system. Understanding where to spend each resource is critical for maintaining a steady progression curve.
| Currency | Primary Source | Best Spending Choice | Upgrade Target |
|---|---|---|---|
| Coins | Wave Clears, Codes | Skill Tree, Weapon Upgrades | Permanent player power, castle health |
| Souls | Defeating Heroes | Minion Unlocks, Minion Upgrades | Army size, minion damage, minion health |
By keeping your currencies separated, you can build a balanced defense. Use your Coins to make your boss character a powerhouse, while using Souls to ensure your army can hold the line independently.
| Upgrade Type | Currency Required | Progression Type | Impact on Gameplay |
|---|---|---|---|
| Weapon Level | Coins | Permanent | Increases player direct damage and swing speed |
| Skill Tree | Coins | Permanent | Unlocks passive buffs for both player and minions |
| Minion Level | Souls | Run-Specific / Permanent | Directly scales minion health, defense, and damage |
If you find yourself failing waves, check which currency you are hoarding. Spend your Coins on the Skill Tree for global buffs, and dump your Souls into your highest-tier active minions.

Q: What is the best way to farm Souls for minion upgrade costs?

Q: Are there any active codes to help with upgrade costs?
Yes, you can redeem the code betheboss in the Settings menu to receive 500 Coins. While this rewards Coins instead of Souls, it frees up your in-game earnings to be spent directly on minion upgrades.
Q: Do minion upgrades carry over between runs?
Yes, permanent minion upgrades purchased with your hard-earned Souls will persist, allowing you to start subsequent runs with a much stronger army from wave one.
