What is a castoroides used for? castoroides battling strategies in ARK: Survival Ascended & Evolved.
If you want their dams for their materials don’t hunt for dams take a tapejara i think the tapejara will work if not a quetzal grab on of the bad suckers and transport them to a nearby lake or river near your base and they will make dams you also might wanna clear the area of baddies
I just drop this guy in some woods right by my house that are carnivore free other than some dilos and i set him on wander (and attack target in case he needs to defend himself) and he just hobbles around collecting wood for me. Then I go pick him up with my argey and drop him by a storage box in my base then I just quickly transfer the wood and thatch and put him back to keep harvesting!
-The Burrito
One of these bad boys can collect 200 wood and 50 thatch from one tree. If you upgrade the damage enough times it will turn into a chainsaw. Can take down 2 carnos easily. I have 2 of them and they harvest wood dam well. Knocking them out is easy but make sure you have like 50 narcs and 25 mejoberries they don’t get hungry very often. If you don’t need wood just out them next to your base as defense.
This is the best creature you can have to carry wood long ways just get an Argentavis and pick him up now you can fly and carry tons of wood and fly easy back to your base. One problem that you have to drop him right next to the tree and ride it so you can get over weight and you don’t have to go beck every few steps becouse you can load him by your self
For Ark Mobile;
-If you want a passive wood supply, don’t tame them. Just let them be and they’ll build a dam (just make sure to pull out all the needed resources like wood, rare flowers, silica pearl, Cementing Paste,etc) so that they can make another dam. But a tamed Castoroide, just put them on wonder and carry them with an Argy and get close to a tree (recommend to level up melee and also weight on your Castoroides). It’s like having a Doedic but it gathers wood :) Hope this helps.

since nobody knows how to build a very good taming pen for creatures like these or theri heres mine:
just take a 3x3 stone foundation (total 9) and get 36 doorways
and place them to make a cube on the foundations
and finish up placing stone floor doing a circle on the doorways
and boom you have got an awesome taming pen where even therizinos cant escape
