A damaged Large Furnace can be repaired where it stands with a hammer. Repairing it from nothing to full costs:

Hammer Placed repair

×250 ×300 ×38

Reduction is how much of that damage type never lands. Damage taken is the rest: at 50% reduction a hit for 100 does 50. A negative reduction means the hit lands harder than it would bare.

From full health (1500 HP), each one placed on it: damage per hit is after its protection. Duds are throws that fizzle and need another throw, not counted in Needed. Costs are for the whole count, crafted from raw materials.
