Castoroides Saddle — Detailed Guide
A saddle that is also a Smithy
Survivors ride a tamed 
Castoroides with the Castoroides Saddle in ARK: Survival Evolved and ARK: Survival Ascended. The description on the ARK Wiki calls the animal a Giant Beaver. The wiki calls this saddle special: with it on, the beaver works as a mobile 
Smithy, in the same way as the 
Argentavis Saddle.
Crafting from the beaver's inventory
How much a Castoroides can carry depends on weight, the ARK Wiki explains, and that lets it craft items of Ascendant quality that a normal Smithy often cannot, given their cost and the station's slot limit. Recipes that call for large loads of heavy material are the catch: depending on its weight stat, the beaver may struggle to craft them.
Engram and materials
The engram unlocks at level 61 for 50 engram points, and our data lists the Smithy as its prerequisite. The saddle is crafted in a Smithy or on an Argentavis Saddle, taking 10 seconds and giving 51.5 XP each. The recipe:
- 290
Hide - 200
Fiber - 180
Thatch - 140
Cementing Paste (or 
Achatina Paste) - 100
Metal Ingot (or 
Scrap Metal Ingot)
Stats, drops and crates
Our records give the saddle an armor rating of 25 and 50 durability. It weighs 20 and does not stack. The Castoroides is listed as a creature that can drop it, and 284 crate types can contain it, such as Astraeos Blue and Astraeos Desert Purple, each with a bonus version. It is listed on 14 maps, among them The Island, Ragnarok, Genesis Part 1 and Fjordur.
