Me favorite way to loot the dams without dying is to get a high weight argie and put it right next to a dam then stay in the middle so you can access both from where you stand go into the dam the beavers won’t get mad until you take stuff then transfer all get on your argie and fly up fast. Also the beavers can’t fly. Then fly somewhere high up and drop the wood and do it again if you want the wood I would store it because if your Argie gets encumbered you can only lift of the ground and they will wait for you to run out of stamina and you’ll die I suggest having a weight of 1k just to be safe.
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.
