Mekanism Gear: MekaSuit, Tools, and Utility Items
Mekanism's end-game gear is powered equipment built from its top-tier materials. This guide covers the MekaSuit and the mod's signature tools.
The MekaSuit
The MekaSuit is Mekanism's modular powered armor. Each piece — the 
MekaSuit Helmet, 
MekaSuit Bodyarmor, 
MekaSuit Pants and 
MekaSuit Boots — is crafted from four 
HDPE Sheet, an 
Ultimate Control Circuit, the matching netherite armor piece, two 
Polonium Pellet and a 
Basic Induction Cell. It is a full end-game investment layered on top of netherite.
Powered tools
- Atomic Disassembler — a powered multi-tool made from Atomic Alloy, Infused Alloy, an Energy Tablet and a Refined Obsidian Ingot.
Electric Bow — a rechargeable bow built with Infused Alloy and an Energy Tablet.
HDPE Reinforced Elytra — an elytra reinforced with Atomic Alloy and HDPE Sheets.
Utility and safety gear
The Jetpack and Free Runners have Armored variants for extra protection, and the Hazmat set (mask, gown, pants and boots from lead) protects against radiation. HDPE Sheet and 
HDPE Rod, made from HDPE Pellets, are the plastic components behind most of this gear.
Where the gear sits in a very large mod
Mekanism carries 368 pages, 200 blocks and 168 items, and the suit and tools are the top of the item half. Getting there means running the ore and chemical chains rather than following a separate gear tree.
Nucleosynthesizing — 21 recipes on 1.21.1, 20 on 1.20.1 — is the endgame category behind the rarest materials, and it is one of the few that barely differs between versions.
The chemical prerequisites are version-dependent
Several processes feeding late-game materials exist only on 1.21.1: Dissolution (23 recipes), Oxidizing (25), Chemical Conversion (24), Washing (7) and Chemical Infusing (4). On 1.20.1 those categories are empty.
That does not mean the suit is unobtainable on the older build, but it does mean any progression guide referencing those steps is describing the newer one.
The workhorse categories
Everything upstream runs through Enriching (322 recipes), Crushing (313), Injecting (91) and Purifying (28). Ore processing is the foundation of the gear chain as much as of everything else.
Practical advice
Build the ore chain to tier before chasing the suit. The materials are gated on throughput rather than on unlocking recipes, so a faster enrichment line shortens the path more than any single craft.
