Be The Final Boss flips the usual Roblox tower defense formula by putting you in the role of the villain. Instead of attacking waves of enemies, your goal is to build a powerful defensive army that protects your castle from heroes attempting to defeat you. Progressing efficiently requires more than simply summoning stronger monsters—you’ll also need to upgrade your skill tree, farm currencies, improve your units, and understand how passives and mutations work together.
This guide covers everything beginners need to know, including the best mythic unit, how to earn Souls and Coins faster, the importance of Shards, and the most effective progression strategy to help you grow stronger without wasting resources.
Redeem Every Available Code Before You Start
One of the first things every new player should do is redeem all active codes. Open the Settings menu, locate the code redemption section, and claim every available reward before spending any resources. Most codes provide a generous amount of Coins and other useful rewards that significantly speed up early progression.
These free rewards allow you to upgrade your skill tree sooner, summon additional units, and build a stronger defense without spending hours grinding. Even experienced players should keep an eye out for newly released codes since they often provide valuable resources.
Upgrade Your Skill Tree First
The Skill Tree is one of the most important progression systems in Be The Final Boss. Rather than spending all your resources on summons immediately, invest in permanent upgrades that improve your overall account. Important upgrades include:
- Higher Coin income
- Increased Soul gain
- Better boss-related bonuses
- Additional unit capacity
- Various passive combat improvements
Because these bonuses apply permanently, every future battle becomes easier. Prioritizing your skill tree early will make farming resources much faster later in the game.
Build the Strongest Team Possible
After upgrading your account, it’s time to organize your army. Every unit occupies one or more deployment slots. Larger or stronger units often require multiple slots, so you’ll need to balance your team carefully instead of filling every space with high-cost monsters. Some examples include:
- Great Warlock uses two deployment slots.
- Cursed Acolyte also occupies two slots.
- Smaller monsters usually only require one slot.
As your skill tree improves, you’ll unlock additional deployment capacity, allowing you to field stronger combinations.
Understand Unit Passives
Every monster comes with a unique passive ability that can dramatically affect battles. Some passives activate automatically after gaining enough energy, while others provide continuous bonuses such as burn damage or crowd control. For example, certain units can:
- Burn multiple enemies at once
- Deal damage over time
- Attack several targets simultaneously
- Trigger powerful area attacks
Instead of choosing units based solely on Power, pay attention to how their passives work together. A balanced team often performs much better than one filled with random high-power monsters.
AFK Farming Is One of the Best Ways to Progress
Once you’ve deployed your team, you can enable Auto and begin fighting automatically. This lets your monsters continuously defend your castle while you farm resources with minimal effort. AFK farming is especially useful for earning:
- Coins
- Souls
- Enemy drops
- Shards
- Experience
The longer your team survives, the more rewards you’ll accumulate.
Best Mythic Unit
If you’re fortunate enough to obtain a Mythic monster, one of the strongest overall choices is:
- Mighty Orc
The Mighty Orc offers excellent overall performance and remains useful throughout much of the game’s progression. While future updates may introduce stronger options, it currently stands as one of the safest Mythic investments.
How to Get Shards Quickly
Shards are one of the most valuable upgrade materials in the game. They primarily drop from defeated enemies, making regular combat the best farming method. Some enemies also drop Crystals, which contribute toward later progression systems. Because you’ll need a large number of Shards for upgrades, consistent farming is far more effective than saving resources and upgrading only occasionally.
Upgrade Your Units With Shards
Collecting Shards isn’t enough—you also need to spend them wisely. Each unit can be upgraded using Shards, increasing its combat effectiveness and making your defensive lineup considerably stronger. Rather than upgrading every monster equally, focus your resources on your strongest or most frequently used units first. Concentrating upgrades produces a much larger increase in overall team strength.
Mutations Can Make Average Units Extremely Powerful
One mechanic many beginners overlook is the Mutation system. Sometimes you’ll obtain two copies of the same monster, but one has a Mutation while the other doesn’t. For example:
- Bone Grunt (Normal)
- Bone Grunt (Cursed)
Even if both are the same level, the mutated version can significantly outperform the normal one thanks to its additional bonuses. Always compare duplicate units before deleting or replacing them.
Use Auto Roll to Find Better Units
Rolling for monsters is a major part of progression. Instead of manually summoning every time, enable Auto Roll to continuously summon until you obtain a better rarity. This saves time while increasing your chances of obtaining:
- Legendary units
- Secret units
- Strong mutations
- Better overall team members
If you plan on summoning in large batches, Auto Roll is the most efficient option.
Fuse Lower-Tier Shards Into Better Ones
As you continue farming, you’ll collect many common Shards. These can eventually be fused into stronger versions:
- Common Shards
- Rare Fusion Shards
- Epic Fusion Shards
- Legendary Fusion Shards
Rather than letting low-tier materials sit unused, combine them whenever possible to unlock stronger upgrades later.
Sit on the Throne for a Passive Buff
A small feature many new players miss is the throne inside your castle. Whenever you’re being attacked, sitting on the throne grants a passive bonus that improves your performance during combat. Although it isn’t game-changing by itself, every additional advantage helps during difficult enemy waves.
Keep Replacing Weak Units
Your team shouldn’t remain the same forever. Whenever you obtain a monster with higher Power or better abilities, compare it with your current lineup and make adjustments. Don’t simply chase the highest Power number, however. Consider:
- Passive abilities
- Energy skills
- Area damage
- Damage over time effects
- Team synergy
Mixing complementary units often produces better results than stacking similar monsters.
How to Get Souls Fast
Souls are required for additional summons and continued progression. The fastest way to earn them is by combining several strategies:
- Upgrade your Skill Tree regularly.
- Defeat as many enemies as possible.
- Farm Elite Waves whenever available.
- Increase your Soul Harvest upgrades.
- Keep your team improving so battles last longer.
Since Skill Tree bonuses permanently increase Soul gain, investing there first pays off over time.
How to Get Coins Fast
Coins fuel nearly every progression system, making them one of the most important currencies. To maximize Coin income:
- Redeem every active code.
- AFK farm regularly.
- Upgrade Coin Income in the Skill Tree.
- Win battles consistently.
- Claim all available beginner rewards.
- Use free Spins whenever possible.
The combination of passive farming and permanent upgrades creates a steady flow of Coins throughout your playtime.
Don’t Forget Free Spins
Free Spins are easy to overlook but can provide surprisingly valuable rewards. Possible prizes include:
- Large Coin rewards
- Souls
- Other useful progression materials
Even if the rewards seem random, using every available free Spin gives you extra resources at no cost.
Claim Beginner Rewards
New players also have access to group rewards and beginner bonuses. While these rewards aren’t as valuable as redeemable codes, they’re still worth claiming since every free resource helps during the early stages of progression. Never leave free rewards unclaimed.
Be The Final Boss rewards players who focus on long-term progression instead of chasing powerful units immediately. Permanent Skill Tree upgrades, efficient AFK farming, smart unit management, and regular Shard upgrades all contribute more to your overall strength than relying purely on luck. By consistently improving your account, replacing weaker monsters with stronger ones, and taking advantage of free rewards like codes and Spins, you’ll build a defensive army capable of surviving increasingly difficult waves and protecting your castle against even the toughest heroes.
