Materials
Lift a Cube arm materials guide: material rarities, Strength multiplier ranges, roll behaviour and which rolls are worth building your arms around.
Introduction
Arm materials are the multiplier layer that separates a grinder from a strongman. Opening a chest rolls a randomized arm material, and each material carries a Strength multiplier that applies on top of everything else you have built. Rare materials sit at the bottom of the roll table but multiply Strength by a large factor, which is why a single lucky roll can outpace hours of ordinary push-ups. This page explains material rarities, how rolls behave from a player perspective, and which multipliers are worth building your arms around. Because the developer does not publish a rate sheet, we describe rarity bands and relative multiplier size instead of inventing exact percentages.
Material Rarity Bands
| Rarity | Multiplier | Roll Odds | Keep? |
|---|---|---|---|
| Common | Small | Most frequent | Use early, replace later |
| Uncommon | Modest | Fairly frequent | Keep while bridging |
| Rare | Solid | Uncommon | Keep for the mid game |
| Epic | Large | Rare | Build around it |
| Legendary | Huge | Very rare | Endgame keeper |
Material Rarities
Common material
The most frequent early roll
Uncommon material
A modest multiplier that bridges the early game
Rare material
A solid multiplier for mid-game builds
Epic material
A large multiplier worth reorganising for
Legendary material
The rarest and strongest multiplier
Core Mechanics
Materials work independently of arms but multiply the same Strength number. A chest resolves into exactly one material outcome, and the rarity of that outcome determines the size of the Strength multiplier attached to it. Applying a material does not consume your arms; it stacks on top of them, so the correct mental model is multiplication rather than replacement. Because rarer outcomes are less likely, the practical strategy is volume: open chests whenever you can, keep every material, and apply the largest multiplier to the arm tier you actually use. Exact drop rates are not published, so the odds column on this page is a relative guide rather than a precise probability table.
Advantages
Multipliers are the single biggest source of power spikes in Lift a Cube. A rare material can take the same arms and the same training routine and produce dramatically more Strength per minute, which shortens every remaining grind on the map. Because materials stack rather than replace, a good roll never becomes wasted when you buy a better arm tier; it simply multiplies the new tier as well. Understanding rarity also stops you from discarding an early material that looks weak today but becomes valuable once your base Strength climbs higher. Keeping every roll costs nothing and preserves the option to build around it later, and for free players the multiplier layer is the fairest route to endgame power.
Challenges
Exact material drop rates and multiplier values are not officially published, so everything on this page is community-observed and can shift after a balance pass. Rolls are random, which means progress is uneven: one player may land an epic material early while another grinds for hours without seeing a rare outcome. Because there is no published pity system, budgeting around a specific roll is unreliable, and a material that is optimal today may be outclassed by a new tier the developer adds in a future update. Treat any specific multiplier number you see online as an estimate and verify it in game before building a whole plan around it.

Quick Tips
Open chests as soon as you get them early on. A common multiplier still raises your Strength per minute, and the habit keeps new materials flowing while you save for better arms. Waiting for a perfect roll before using anything simply leaves free power sitting on the table. Re-check your applied materials after every new arm purchase to avoid leaving power unused.
Keep every material, including duplicates. You never know which rarity will become the foundation of your build, and storing a roll costs nothing while discarding it can cost hours if it turns out to be the multiplier you needed. Sort your inventory by multiplier size instead of by rarity name alone.
Re-evaluate applied materials after every new arm tier. Because materials multiply the arm you are using, a build that was optimal with cheap arms may need reshuffling once a faster tier changes your Strength per minute. A five-minute inventory check after a big purchase often finds a better combination. Treat a rare roll as a reason to reorganise your whole build around it.
