Furry pelt of a thrumbo. Luxurious and extraordinarily durable. Used for the highest-quality crafts for its insulation and strength.
Thrumbofur is a type of leather produced when a cook butchers a thrumbo at a butcher table. It is one of the best clothing materials in the game; thrumbofur apparel surpasses all other leathers in terms of protection, and it is one of the best insulators. High quality ones can even match flak vests and helmets in terms of armor value.
The following animals provide thrumbofur.
Thrumbofur is one of the two most protective and insulative textiles in the game and is the premier choice for dusters and other protective clothing. Of all the other textiles, only hyperweave is comparable. The question of superiority is not a simple one however. Thrumbofur offers slightly better sharp armor and exceptional cold insulation, while the hyperweave offers better blunt armor, significantly better heat armor and slightly better heat insulation. Due to the low blunt armor offered by clothing in general, the difference in blunt armor is only likely to be relevant at high quality levels and only on dusters, as the AP of most blunt weapons will completely nullify the little protection offered by the items. The heat armor is significant though, offering good protection against inferno cannon that become common in the late game.
Thus, while Thrumbofur will perform slightly better against the most common damage type, hyperweave is a better generalist. The difference is likely moot however, as both materials are uncommon enough that the player will rarely have to choose between them. Hyperweave is especially uncommon.
Thrumbofur should be preferentially turned into dusters to fully exploit its protective stats, and only if there is a significant surplus should it be turned into pants and button-down shirts. That said, even as less protective items of clothing, thrumbofur still offers decent protection. Even a pair of Normal Thrumbfur Pants have a 12.6% chance to outright nullify a bullet from an assault rifle, and another 12.6% chance to half the damage.
For use in furniture, thrumbofur's exceptional beauty factor and market value make for very good buffs to room quality, however this is a waste of its potential. Sculptures are a better way to improve room quality, while the thrumbofur itself is better used to protect pawns as clothing.
