MegaBonk Proc Guide: How Proc Chance Works

In MegaBonk, proc effects are game-changers for dealing massive damage. Items and weapons with on-hit triggers become exponentially powerful when optimized, making them essential for surviving late-game bosses or endless waves.

Understanding Procs

A proc triggers when landing a hit, activating effects like poison, explosions, or chain lightning. Each item has an independent chance to proc, calculated per attack. Fast-attacking weapons or those with multiple projectiles benefit most by rolling these chances more frequently.

Proc Mechanics Deep Dive

Proc chances are percentage-based and stack across items. For example:

Moldy Cheese: 40% poison chance
Spicy Meatball: 25% explosion chance on kill

Carrying multiple proc items lets attacks trigger multiple effects simultaneously. The Overpowered Lamp is especially potent, granting extra proc rolls per hit.

Top Proc Items

Essential Picks

Overpowered Lamp – +1 proc roll chance
Spicy Meatball – 25% AoE explosion on kill
Dragonfire – 15% burn-inflicting fire
Lightning Orb – 25% lightning strike with stun
Moldy Cheese – 40% poison on hit

Situational Choices

Soul Harvester – homing souls on kill
Toxic Barrel – poison waves when damaged
Slutty Cannon – kill-triggered missiles
Bloody Cleaver – lifesteal with Bloodmark

Optimizing Procs

Prioritize:

Attack Speed & Projectiles (via Tomes)
Multi-Hit Weapons like Bone, Revolver, or Aura

Defensive weapons like Aegis can sustain you while procs handle damage.

Build Strategy

Stack multiple proc items for overlapping effects. Once you have 3+ procs, focus on attack speed over raw damage. Overpowered Lamp is a must-grab to amplify triggers.
