Outstanding wood collectors. Mine has 770 weight and can carry 3K wood plus rider. Holds wood at 1/5 weight and can be used as mobile smithy. This teamed with a doed can construct a base in minutes. Must have.
If you ever encounter a casteroids around, there is likely a dam nearby( it looks like a tent made of sticks). They contain lots of wood, cementing paste, and rare ingredients and resources(silica pearls, rare flowers and mushrooms). However, make sure you get rid of the beavers first, since they become aggressive if you loot the dam.
If you are looking for a safe place with no carnos or allos around the beaver dams, you've come to the right spot. I play on Ark mobile and i live in the Southern Isles. Here are the coordinates for which i find my beaver dams: Lat 98, Lon 58. Also, heres a tip if you don't have a pteranodon. Just bola the beaver and shoot it in the head with a bow. I got a really strong bow from the pursuit Hunt: Dilophasaurus and it works well on the beaver. I suggest doing the pursuit if you are a beginner to get the bow. 30 arrows should do it for a small level. I hope this helped! Like so that beginners can see!
