Drag a line to lay up to 40 segments; neighbors join up and diagonal lines still seal. The Wall button builds your best tier, and its icon shows which; the notches on it pick a cheaper tier (or press the Wall key again while placing). To upgrade old Walls, rebuild them: drag a new line over them. You pay the difference at once, and Laborers rebuild each segment while it stands; new tiles in the same line are built as usual. Selected segments (drag a box over them, or Select line) can also be rebuilt from their panel. Tiers: Palisade 240 HP for 8 Wood; Stone-footed (March) 384 HP for 5 Wood + 5 Stone; Stone (Sovereignty) 576 HP for 2 Wood + 10 Stone. A segment keeps its tier until you rebuild it at a higher one: drag a new line over it and pay the difference.
