The Castoroides is an excellent wood gatherer and transporter, with useful weight reduction for wood, stone, and other building materials. Its saddle functions as a mobile smithy, making it valuable for crafting on the move, while its mobility and combat ability make it a versatile mount. Wild Castoroides build dams containing resources such as cementing paste, silica pearls, rare flowers, and mushrooms, but disturbing a dam provokes nearby beavers.
