Ashlar Basalt

Ashlar is finely cut stone made by an expert mason. Ashlar stone is an especially decorative building material that comes in a variety of styles based on the type of rock used.

Notes

Ashlar Basalt is a high-tier decorative building material crafted by a skilled mason, placing it in the late-game construction phase. As a tier-5 block, structures built from it provide an excellent room value, significantly boosting residents' housing-based experience gain. A practical tip is that, due to its high tier, crafting a stock of ashlar blocks can dramatically improve the progression speed of any settlement's housing and crafting upgrades.
