# Reading the Math | Big Mech Energy Idle Wiki

MechMaxxing shows its work. Hover any attack node for the full stair-step:

- **Damage** = (base × level + incoming Power × flow-scale) × (1 + Σ additive bonuses) × Π multiplicative bonuses.
- **Tuners add, Boosters multiply.** Two +power tuners on one attack stack additively; a Booster (amplifier) inline multiplies the whole Power feed. Stack adds early, multiply last.
- **Core taps** divide (÷N badge) when one feeds several attacks, and sum when several feed one attack. The "Core taps" readout shows how many you're using.
- **Crit** = base crit% + Σ crit tuners, at base crit-mult + Σ crit-damage tuners. **Fire rate** rises as haste tuners cut cooldown, hard-capped at 20 percent total. Haste is a garnish, not a build.

Net: focus a few strong attacks early (few taps), then widen as Ascensions grow your tap count, or go all-in and supercharge one.
