Pickup rules and multiplier math

Megabonk Powerups Explained

Know what a powerup is, how the two powerup stats differ, and which pickups are safe during the Hero Sword challenge.

Items are not powerups: they are separate categories.

Quick Answer

Powerups are temporary in-run pickups, not Items. Items, Shrines, weapon or Tome level-up choices and XP are separate systems. Powerup Multiplier scales an applicable effect value; Powerup Drop Chance scales the relevant drop roll.

What Counts as a Powerup?

Run rewardPowerup?Hero Sword run
Temporary floor powerupYesDo not collect.
Inventory ItemNoStill forbidden by the separate no-items rule.
Shrine rewardNoStill forbidden by the no-Shrines rule.
Weapon or Tome levelNoAllowed.
XP pickupNoAllowed.
Chest rewardNoAvoid it because accepting an Item fails the run.

Fast rule: a short-lived effect collected from the floor is a powerup. Inventory rewards, Shrines and level-up selections keep their own category.

Powerup Effects to Recognize

The presentation may change by version, but temporary pickups fall into useful effect groups.

Offense

Damage boosts

Temporary offensive spikes, not permanent Damage upgrades.

Mobility

Speed boosts

Short movement bursts, separate from Movement Speed stats.

Defense

Protection effects

Temporary protection or invulnerability, not persistent Shield.

Recovery

Immediate recovery

A floor recovery pickup resolves when collected.

Utility

Temporary utility

Short-lived utility delivered through the pickup system.

Not included

Items and upgrades

Clover, Gym Sauce, Tomes and Shrine rewards are not powerups.

How Powerup Multiplier Works

The stat is an x-value. A 10% increase from 1.00x produces 1.10x.

FormulaModified value = base powerup value x Powerup Multiplier

Duration example

10 seconds x 1.10 = 11 seconds.

Magnitude example

20 units x 1.25 = 25 units. The UI may round.

Boundary: do not apply this formula to Items, Tomes, Shrine rewards or character passives.

Powerup Drop Chance Is Relative

FormulaEffective chance = source base chance x Powerup Drop Chance

With a hypothetical 5% base chance, 1.20x produces 6%, not 25%. The 5% only demonstrates the math; it is not a claimed universal base rate.

Do not assume this stat also raises chest frequency, Item rarity or Luck unless a current effect explicitly links them.

Hero Sword Challenge Checklist

The objective separately forbids Items, powerups and Shrines.

  1. Collect XP and level normally. Weapon and Tome choices are allowed.
  2. Route around temporary floor powerups. Leave space around mixed pickup piles.
  3. Do not take Items. Avoid reward chests and Item vendors.
  4. Do not use Shrines. Even a stat-only reward is disallowed.
  5. Kill the Stage Boss before taking its reward.

Use the Hero Sword unlock guide for the complete build and run plan.
