Build time and upgrade cost by level

Every upgrade to Sawmill costs food, wood, stone and iron in a fixed 1 : 0.8 : 0.5 : 0.4 ratio, and takes a time derived from this plot's own base of 4 seconds. The curve has two phases: it climbs gently to level 26 — the end of the opening ramp, which the whole early game is paced around — and compounds harder above it, so the summit costs a real hoard as well as real patience.

Wood output by level

Output is strictly linear in the plot's level: 6 wood per second for each level standing — the realm runs at 3× speed, so the plot's own base figure of 2 a second is multiplied by that, the same factor every build timer on this page is divided by. Seasons then multiply it — a winter cuts food production to 45% of this and gathering to 60%, and a Long Night is harsher still — as do studied production research and the favour of your smallfolk. The Intro Era — the pre-alpha's standing acceleration, applied to every producer in the realm — multiplies the whole stack by 2.5× on top of that, so a level of this plot is really worth 15 a second while it lasts.

What wood is spent on

Wood pays for every construction order, the shafts and stakes of your traps, and the engines that clear somebody else's. Every building upgrade in the game bills the four resources in a fixed ratio, and wood is charged at 0.8× the headline figure — the third largest share of the four.

How long this plot alone takes to pay for one building upgrade in wood.

The second plot — Sawmill II

At Keep 15 a second plot of this kind opens — Sawmill II. A second timber yard for a growing city. It is the same building in every respect that matters: the same 4-second base, the same cost curve, and the same 2 per second per level. That is what makes Keep 15 the most valuable single level of the opening: it does not improve this resource's income, it doubles its ceiling.

Both sawmill plots held at the same level, against one plot alone.
