Megabonk Item Guide

Overview

In Megabonk, most items can only be proc'd (triggered) by weapon attacks. However, there are 7 items that can proc other items when they deal damage (example: Holy Book can proc the Spicy Meatball).

Items That Can Proc Other Items

Item	Proc Coefficient
Cactus	0.5
Electric Plug	0.5
Toxic Barrel	0.5
Shattered Knowlegde	0.5
Holy Book	0.5
Mirror	1.0
Cursed Doll	1.0

How Proc Coefficient Works

Proc coefficient determines the percentage chance of triggering other items. It acts as a multiplier for the proc chance of items that get triggered.

Proc Coefficient = 1.0 (Full Proc Chance)

Items with a proc coefficient of 1.0 (Mirror, Cursed Doll, and most projectile weapons) trigger other items at their full proc chance. This means:

Proc chances work at their full percentage (e.g., a 2% proc chance stays at 2%)
These items behave exactly like most projectile weapon attacks when triggering other items. For instance if an item says it has a 40% chance to do something, it has a 40% chance (unless the item uses hyperbolic scaling, in which case it might be slightly less or more. But this is not really relevant for understanding the concept here)

Proc Coefficient = 0.5 (Half Proc Chance)

Items with a proc coefficient of 0.5 (Electric Plug, Toxic Barrel and Holy Book) trigger other items at half the proc chance. This means:

Proc chances are halved (e.g., a 2% proc chance becomes 1%)
These items are less likely to trigger other items compared to weapons with proc coefficient 1.0. So if an item says it has a 40% chance to do something, it really has a 20% chance if triggered from an item with a Proc Coefficient of 0.5

Weapon Proc Coefficients

Most projectile weapons have a proc coefficient of 1.0, meaning they trigger other items at their full proc chance. However, some multi-hit weapons (like Axe, Aura, etc.) have a slightly lower proc coefficient to balance their ability to hit multiple enemies per attack.
