BUNNYBastion Resource Management Guide: Gold, Gems & Upgrades
Updated 2026-06-13

Understanding the Core Resources in BUNNYBastion
BUNNYBastion features a streamlined resource system designed to keep every 10-minute run tense and tactical. Unlike sprawling strategy games, this Roguelite tower defense focuses on three primary resources: Gold, Gems, and Upgrade Points. Each plays a distinct role in how you build your defenses and scale your power.
Gold is the most common resource, earned by defeating enemies and completing waves. It is used to construct and repair towers, activate special abilities, and purchase temporary boosts during a run. Gems, on the other hand, are rarer and persist between runs, serving as the premium currency for unlocking permanent upgrades and new starting loadouts. Upgrade Points are earned through in-game milestones and are exclusively spent on the meta-progression tree that enhances your base stats and unlocks new strategic options.
Understanding the flow of these resources is critical. A common mistake new players make is hoarding gold for expensive towers while neglecting cheaper, more efficient defenses that can compound your income. Efficient resource management means knowing when to spend and when to save.
Gold Economy: Earning, Spending, and Snowballing
Gold is the lifeblood of every BUNNYBastion run. You start each match with a modest amount, but your ability to generate more depends entirely on your early decisions.
Primary Gold Sources
- Enemy Kills: Basic enemies drop small amounts of gold. Elite enemies and bosses drop significantly more.
- Wave Completion Bonuses: Each cleared wave grants a lump sum of gold. The amount increases with each subsequent wave.
- Interest and Investments: Some upgrades and character classes provide passive gold generation or interest on unspent gold. This is a key snowball mechanic.
- Treasure Rooms: Optional challenge rooms found between waves often contain gold caches.
Spending Priorities
Your first few waves are the most important. We recommend the following spending hierarchy:
- Essential Towers: Place at least 2-3 basic towers on the path to handle the first few waves.
- Upgrade Key Towers: Focus upgrades on a single tower line rather than spreading resources thin. A tier 2 tower is often better than two tier 1 towers.
- Utility Purchases: Items that grant bonus gold or reduce upgrade costs pay for themselves quickly.
- Avoid Overbuilding: Do not build towers you cannot afford to upgrade. Unupgraded towers become useless after wave 5.
Pro Tip: If you find an upgrade that grants +1 gold per kill, prioritize it immediately. This single upgrade can double your income by wave 10, allowing you to snowball into a dominant position.
Gems: The Persistent Currency for Meta-Progression
Gems are the most valuable resource in BUNNYBastion because they carry over between runs. You earn gems by completing achievements, defeating bosses for the first time, and finding hidden caches in the game's environments.
How to Farm Gems Efficiently
- Focus on Achievements: Many early achievements reward gems. Check the achievement list in the main menu and target the easiest ones first.
- Boss Runs: Each unique boss you defeat for the first time drops a substantial gem reward. Use the
/en/guides/boss-guide/to learn their patterns. - Daily Challenges: If available, daily challenge runs often offer bonus gem payouts.
- Treasure Hunt: Explore every node on the map. Secret rooms and breakable objects sometimes contain gems.
What to Spend Gems On
Gems are best used on permanent account upgrades and new starting loadouts. Avoid using gems for temporary in-run boosts, as that is a poor return on investment.
Long-Term Strategy: Save your first 500 gems for the "Gem Forge" upgrade in the meta-progression tree. This upgrade increases all future gem drops by 20%, making every subsequent gem purchase easier to afford.
Upgrade Points: Building Your Permanent Power
Upgrade Points are earned by leveling up your account, completing specific challenges, and advancing through the game's progression system. They are spent in the Progression Tree, which is accessible from the main menu.
Key Upgrade Paths
- Defense Tree: Improves tower damage, range, and attack speed. Prioritize this if you favor a static defense strategy.
- Economy Tree: Enhances gold generation, starting gold, and gem drop rates. This is universally useful.
- Survivability Tree: Increases your base health, shield capacity, and healing rate. Essential for aggressive playstyles.
- Utility Tree: Unlocks special abilities, additional loadout slots, and unique items.
Optimal Spending Order
For new players, we recommend the following order:
- Starting Gold (Economy Tree): +50 starting gold allows you to build a stronger early defense.
- Tower Damage (Defense Tree): +10% tower damage helps clear waves faster.
- Gem Drop Rate (Economy Tree): Unlocks the passive gem income that accelerates all future upgrades.
- Loadout Slot (Utility Tree): A second loadout slot lets you prepare for different enemy compositions.
Warning: Respeccing Upgrade Points is not free. The cost increases with each respec. Plan your build carefully by consulting the /en/guides/progression-guide/ for a detailed breakdown of each node.
Advanced Resource Management Strategies
Once you understand the basics, you can employ advanced strategies to maximize your efficiency in every run.
The 3-Wave Rule
Never hold more than 100 gold at the end of wave 3. If you have excess gold, spend it on a tower upgrade or a utility item. Hoarding gold early misses the opportunity to snowball through interest and faster wave clears.
Resource Synergies
Certain character classes and items create powerful resource synergies. For example, the "Merchant" class increases all gold gains by 15% but reduces tower damage by 10%. Pairing this class with the "Interest" item (which grants 5% of unspent gold every wave) creates a compounding economy that can fund an overwhelming late-game defense.
When to Save vs. Spend
- Save: If you are within 2 waves of a major upgrade (e.g., a tier 3 tower), save gold to afford it immediately.
- Spend: If you are struggling to survive the current wave, spend gold on repairs or cheap towers. Survival is always more important than future planning.
- Gem Spending: Never spend gems during a run unless you are on a boss wave and need a critical revive. Gems are for the meta-game.
Common Resource Management Mistakes to Avoid
Even experienced players fall into these traps. Avoid them to maintain a healthy economy.
- Over-upgrading Early Towers: Upgrading a tier 1 tower to tier 3 in the first 3 waves is inefficient. The cost could have built two tier 2 towers, which provide more total damage.
- Ignoring Passive Income: Upgrades that grant passive gold or gem income are often undervalued. They provide returns every single wave, making them some of the best long-term investments.
- Selling Towers at a Loss: Selling a tower only returns 50% of its total investment. Avoid selling unless you absolutely need the space or gold for a critical purchase.
- Neglecting the Economy Tree: Players who rush pure combat upgrades often find themselves starved for gold by wave 15. A balanced investment in the Economy Tree ensures you have the resources to execute your strategy.
