# Terminology | Big Mech Energy Idle Wiki

The canonical names, so nobody (including the CORE) gets confused.

- **Mech**: your whole machine. Its body tier is the **Chassis** (Scrap-Bot through Dyson-Frame); leveling the Chassis spends Scrap.
- **MechMaxxing**: the wired power graph inside the Mech. Parts are wired under a **Weight** budget; the **Mech Core** is its one intrinsic power source.
- **Parts**: looted modules (Attack, Power, Booster, Tuner, Utility, Frame) in tiers Nerfed through Based from drops, Unit and GOATED from the Foundry.
- **Wave**: one batch of enemies. Every 10th wave ends in a **boss**, a bigger wave machine. Your **frontier** is the highest wave reached.
- **Enrage**: the per-fight damage ramp on every enemy. Waves gain 1 percent per attack, guardians 2, overlords 3. It resets each new encounter and exists so nobody face-tanks forever.
- **Overlord**: one of eleven named bosses fought in a **duel** you start from the Overlords tab. Beating one authorizes an **Ascension** and can unlock a system. Not a wave boss.
- **Ascension**: uploading into the next Chassis. Run resets; MechMaxxing, Parts, Components, Cores, Drones and Pets persist.
- **Drones**: the Salvage Drone Bay. Drones either fly **Strike Sorties** (idle missions for Components and Caches) or stay home and auto-loot Scrap on the field.
- **Pets**: shrunken wave machines that follow you and grant small multiplicative bonuses. Not drones; drones work, pets vibe (and also work).
- **Training Yard**: Sparky Boi's obedience yard. Benched pets run timed trials for +1 level and Scrap.
- **The Foundry**: Sir Loin's part-fusion forge. Three spare duplicates plus Components become one part a rarity higher.
- **The Smelter**: Sir Cumference's furnace. Spare parts melt into **Alloy**, which buys permanent Weight, Storage and drone bay capacity.
- **Supply Lines**: Sir Pent's rail network. Track between cleared segments pays a capped Scrap bonus; loops pay extra.
- **Hostile Takeover**: MechCorp's stock ledger. Staked Scrap pays Components dividends; buyouts grant a capped permanent bonus.
- **Compute Grid**: the Data Center's racks. Intrusions yield **Compute**, which raises CPU and Storage and eases the booster stacking penalty (Lattice Conductance).
- **Districts**: the city living on your legs. Citizens staff Housing, Factory, Lab and Arcade for small capped global bonuses.
- **Star Harvest**: the Dyson swarm. Satellites boost Mech Core power up to double; fifty completes the swarm and reveals **Reboot**.
- **Currencies**: **Scrap** (Chassis and bay levels), **Components** (Part and Core upgrades), **Cores** (permanent Core upgrades, earned by Ascension).
