Be extremely cautious when taming these guys can destroy all ur armor with one spit. I also don't suggest attacking them bc that will break ur weapons real fast. If u r in a cave either avoid it or dodge it's spit while shooting it. It is a passive tame that requires spoiled meat or broths of enlightenment. You need to use bug repellent when taming it and I suggest also wearing gillie for extra safeness. Once tamed they are best used as turrets bc they don't have great stats and they have a turret mode after all why not use it?
Thanks to the Halloween event where these SOBs spawn anywhere they like near my base I've discovered they can slide under gates......you expect to be safe from land creatures, BUT NO. Current death count from unexpected attacks at 2.
Ranged attacks will be your best friends. All of this creatures attacks shred armor durability. Attacking it with melee will also destroy your weapons durability as well as damage you. It's like stabbing a corrosive spike wall. If you are using a tame make sure it has high health or a way to heal quickly.
Never. I repeat never use a melee weapon on this. It will just melt from the acid blood. You might aswell strip naked too when fighting them because even your flak can be melted by their acid in 1 hit.
When you’re going spelunking, bring a Carno or something around those lines. They hold up fairly well against the arthro and so far i have not lost a single piece of my armor while fighting on my tame. (Don’t forget stimberries)
Probably a good idea to apply the same rule for fighting Onycs, that is, avoid melee. Their acid can hit you on smaller mounts you would usually bring in caves. They can be hard to spot in water and against uneven cave walls, but their oil-puddle-like iridescence can give them away if you look hard enough.
