Composites Skill Book
Notes
The Composites Skill Book is a research item that unlocks the Composites specialty, a high-tier skill tree for advanced materials. It is crafted at a Research Table and can produce unlimited skill scrolls for other players, making it essential for late-stage technology like reinforced concrete and composite blocks. Because it costs 4 or more stars to learn (per the standard tiered pricing) and triggers the escalating specialty cost penalty, a town should coordinate on who researches it rather than having multiple players waste resources crafting duplicate books.
