Module Labs

Last verified 2026-07-29 · 11 data tables

Module labs are a set of lab researches focused on your modules. They cover how often bosses drop common and rare modules, how many shards you earn from various sources, and how much it costs to level modules up. Later labs also let you unmerge modules, gain more from shattering, and ban unwanted effects when rerolling.

Each lab is unlocked through Milestones at a specific tier and wave, and most have multiple levels that stack their effect as you research them.

— Common Drop Chance

This lab is unlocked in Milestones at Tier 4 Wave 70. It raises the chance that bosses drop common modules, which matters because the base common drop chance starts at only 2%.

The lab has 10 levels, and maxing it adds a total of 1% to your common drop chance. See the level table below for the per-level values.

— Module Shard Cost

Unlocked in Milestones at Tier 10 Wave 40, this lab reduces the shard cost of levelling up your modules.

It has 30 levels, and at maximum research it cuts shard costs by 30%. Given how expensive higher module levels become, this is one of the more valuable long-term module labs. The cost per level is shown in the table below.

— Module Coin Cost

This lab is unlocked in Milestones at Tier 10 Wave 40 and lowers the coin cost of levelling up modules.

It has 30 levels and provides a 30% reduction to coin costs when fully researched, pairing naturally with the Module Shard Cost lab to make upgrades cheaper overall.

— Rare Drop Chance

Unlocked in Milestones at Tier 10 Wave 40, this lab increases the chance that bosses drop rare modules. The base rare drop chance is 0.5%, so every point here is a meaningful relative gain.

The lab has 10 levels and adds a total of 1% to your rare drop chance at maximum. The table below shows the per-level progression.

— Unmerge Module

This lab is unlocked in Milestones at Tier 8 Wave 20 and has a single level. Once researched, it lets you reverse module merges.

How an unmerge resolves depends on how the module was made. If the merge required a duplicate epic+ module, unmerging returns the lower-level module along with that epic+. If the merge accepted any module of the right rarity, unmerging instead converts the module into shards of the unmerged type. The table below covers the specifics.

— Shatter Shards

Unlocked in Milestones at Tier 16 Wave 40, this lab increases the shards you earn when shattering modules.
