I had a spino. He was black with dark-blue mixed into him, mostly on his fin. I named him Betta because of that. Anyways, spinos are basically the rexes of the water. These guys can go from quadrupedal to bipedal and have very rapid DPS. They also tend to be very, very, ADHD positive and are scarily fast if you’re low-level. Usually if you run from their lake home (or away from the water), they’ll lose interest and leave you be until you return.
If you are having a hard time finding spino's in their respective spawn zones (especially Ragnarok), kill all the fish in that area. They share the same spawn capacity and can be out spawned by coles! ( up vote so Rag players know!!!)
