The Cactus Item in Megabonk is a powerful passive that retaliates when you’re hit—launching damaging spikes at nearby enemies. Its damage scales with Thorns, making it an ideal choice for tanky, damage-reflect builds.
How to Unlock the Cactus Item in Megabonk, you’ll need to complete a specific quest involving Thorns damage and cactus enemies.
Unlock Requirements
- Objective: Kill 100 Cactus enemies using Thorns damage
- Hero Required: Bush
- Location: Desert (Tier 1)
- Difficulty: Hyper Mode
This quest can take several attempts, depending on how lucky you get with enemy spawns and Thorns tomes.
Pre-Run Setup
Inventory Loadout:
Weapons:
Primary: Bush’s starter weapon
Secondary (optional): Shotgun (to help clear space, not kill cactus)
Tomes (choose 3):
Thorns (Mandatory): This is your core damage source. Always pick it when it appears.
Armor: Boosts survivability, helps trigger Thorns safely.
Bloody Tome: Provides health sustain via life steal. Synergizes well with tank builds.
Note: You can have up to 2 weapons and 3 tomes active. If you accidentally pick more than needed, visit the shop during a break and sell off extras to stay focused on your Thorns setup.
Early Game
Wait for Thorns: Do not kill cactus enemies until you’ve found the Thorns tome. Killing them with direct weapon damage won’t count toward the quest.
Positioning: Use right-click to aim your crosshair away from cacti, so your shots don’t accidentally kill them. Let them run into you and take Thorns damage.
Weapon Management: Avoid upgrading your weapon too much. High weapon DPS may outpace Thorns damage and ruin your run.
Mid to Late Game Tips
Tank Up: Prioritize items that give armor, health regeneration, or life steal. You want to stay alive while absorbing hits to trigger Thorns.
Avoid Evasion: Evasion causes you to dodge hits, which prevents Thorns from activating. It directly counters your strategy—never pick it during this run.
Be Patient: Cactus enemies can appear at any time, even in the final minute of a run. Stay calm and play it safe. Don’t panic if you’ve only gotten a few by mid-game.
This challenge is about control, not speed. Thorns builds work best when you manage your positioning and take controlled hits.
You’ll likely need a few runs to get lucky with both Thorns tomes and cactus spawns. Stick with it—the payoff is worth it.
Unlocking the Cactus Item is a satisfying milestone for defensive players in Megabonk. With a little patience and the right setup, you’ll be punishing enemies every time they dare touch you. Focus on Thorns, manage your weapons, and embrace the tank life.
