Summary

The Tempest Mill is the second tier of the tempest branch (T2), an evolution of the basic Wind Turbine. Its base is slightly above T1 (step 16, cap 6), but the weather multipliers are stronger: rain ×2, thunder ×3.5, with an overall cap of 24 EU/FE/tick (the reachable peak is 21). In clear weather it's weaker than the Sky Mill, but in rain and thunder it's an exciting "storm-catcher". It is obtained only through evolution of the basic turbine with a Lunar Evolution Chip; it has no crafting recipe.

Energy

The turbine only produces power and never accepts incoming energy. An 8000 EU/FE buffer, LV-tier output. Energy is emitted from the back face only — same as T1, so the cable on the back wall keeps working after evolution. The other 5 faces are inert.

Generation

As with T1, the base follows the wind curve (full base only at y 189–192, zero above y = 248), but the cap is a bit higher (6) and weather hits harder: in rain the base is multiplied by 2, in thunder by 3.5, with an overall cap of 24 EU/FE/tick. In rain the Tempest Mill already beats what T1 does in a thunderstorm, and in a thunderstorm in the y 189–192 band it puts out 21 EU/FE/tick — more than any other LV generator. That band is narrow, only 4 heights: at y ≈ 159 the same thunderstorm gives 11 EU/FE/tick. In clear weather it's weaker than the Sky Mill (base 6 vs 8), which is the price of that peak.

Altitude, sky and weather are recalculated roughly once every two seconds; between recalculations the rate stays the same.

Blade clearance and rotor interference are exactly the same as on T1: the rotor needs a clear 2×2 square in front of the turbine, and overlapping blades with a neighbouring turbine stops both (even in a full thunderstorm). Full rules and the diagram are in the T1 spec.

Interface

• Type: container — energy bar (tooltip on hover), the central rotor slot and status indicator in the same positions as the basic turbine. While the turbine runs, the status row shows the current output in EU/FE/tick; while it is stopped, the reason. No chip slot and no evolution progress (T2 is a leaf — it doesn't evolve further).

Block Properties

Recipes

The Tempest Mill isn't craftable. The only way to get it is to grow it from a basic turbine: insert a Lunar Evolution Chip and let it work under open sky with a rotor installed. The stored energy carries over on evolution.

• Crafting: none. The block is not available from a crafting table.
• Evolution (the only way to obtain it): a basic Wind Turbine + rotor installed + a moon alignment chip + accumulated open-sky time → turns into the Tempest Mill, keeping the energy it had stored.

Wear warning

When the rotor's remaining durability falls below the threshold - the smaller of 10% of its current max and 120 points - a running wind mill creaks now and then and puffs smoke from the hub of the blade disc; the less is left, the more often, and over the last few percent the smoke gets heavier. So the wear is noticeable on the way to the tower. A new or barely worn rotor, an empty slot and a stopped mill (no wind, no open sky, blocked blades) stay silent. The threshold is taken from the current max, so a repair at the bench ends the warning. A mute chip silences the creak; the smoke stays. The threshold, the window and the pauses are knobs wornComponentCue* (generators section); the lightning rod does not do this.
