A semi-arch covered with plaster
Category: Windows and Doors - Arches
Semi-Arch (Plaster) is a half-arch building piece finished in plaster over Stone. Two semi-arches meet in the middle to form a full archway, or a single one springs from a wall to a pillar, giving doorways and open passages a curved top instead of a square frame. The plaster finish gives it the smooth pale look of the Arches set.

In the Build Tree
The plaster arch pieces are taught together by their plan, which is looted rather than available from the start. Pair this piece with the full Arch (Plaster) and the wider Large Arch (Plaster) for taller openings, and use the Arch Wall (Plaster) to fill the space above an arch. A matching Semi-Arch (Stone) offers the same shape with a bare stone face.

Tips
Build the supporting Walls or Pillars and Beams first, then spring the semi-arch from them so it has something to rest on.
Mirror two semi-arches across an opening to close a full arch cleanly, keeping both halves at the same height.
Plaster pieces share the durable stone health pool, so they hold up far better under attack than the early stick and straw tiers.
Progression Notes
Semi-Arch (Plaster) is part of the crafting progression chain rather than a standalone collectible. Use the recipe, station, and ingredient rows to trace what unlocks it, what it consumes, and which linked upgrades or materials should be prepared before crafting it.
