The One Loop That Runs Season 2

Two personal buildings drive the Polar World economy, linked by two resources:

BuildingWhat it does
Titanium Alloy Factory ×5Produces Titanium Alloy continuously. Upgraded with Coal — a higher level means more Titanium per hour. You get four (No.1–No.4) plus a fifth from the Weekly Pass (produces only while the pass is active).
High-heat FurnaceHeats your base (the thing keeping you out of the −20°C lockout) and is your biggest personal season-ranking score. Upgraded with Titanium Alloy; burns Coal to stay lit.
The flow

Coal → Factories → Titanium Alloy → Furnace → warmth + season points. Coal is the raw input (from Digging Strongholds, donations and events); Titanium Alloy is the intermediate the factories make; the Furnace is the payoff. Both buildings cap at Lv 30 and both vanish at season end — and any leftover Coal and Titanium Alloy is converted to Profession EXP, so nothing you bank is wasted (see the Profession Point Allocation guide).
