Very similar to a beaver. I like to think of them as desert beavers. They act as a smithy and have 1/5 of weight of wood on vanilla and 1/10 weight with stack mods. They also have reduced weight for thatch. They have a very quick attack so can be used as attack mounts, speed of attack similar to raptor. However, the spines aren't that good, although dealing torpor, do little damage and are a HUGE drain on stamina
Gathers wood fast and carries it at 1/5 weight stone is 1/2. Weak on the sides so if you really like this dino to patrol keep another dino with it to aid. Excellent at killing mantis to gathering organic polymer and chitin.
I have 12 on platforms 4 pillars high scattered around my base. I have an issuse with dino spawns in the base. So they act as a long range needle launcher. Weigh down with sand because its weight isnt affected by the dragons buff. Set all to long range aggressive and u have a protected base. Add a few plant X for added assurance. I no longer have spawn problems. Found a ready to tame terror bird today too pretty neat.
No longer carries wood at 1/5 weight, now carries at 1/2 but can now be carried by argentavis and can farm wood similar to farming metal with an argentavis and anky, upgrade melee damage to get the most wood possible.
