These guys, when killed, give you lots of chitin. On Ragnarok there's a castle near the swamp at the top of the map full of these guys. Grab a high lvl argie and you'll have stacks of chitin very quickly.
After the creatures replaced this many considered it useless now.to re-new this it would be nice if it had a full power climb,like megalania,maybe hav it be able to spin webs to trap creatures no-larger than a carno,to top it all off hav it spin webs around your base that produce silk and when wild dinos try to attack they get caught in the web.
Don’t underestimate these things. A dilo and an araneo set on turret mode completely blinds any would be attacker. Pair that with a raptor for the pin, and an onyc for megarabies and the armor wreck, that player won’t know what hit them.
