Okay so I was moving by base from south 2 to the volcano and the only flyer I had was a pt so I started moving my stuff when I was ambushed by a rhyiognatia (rhyio). I was dodging its blasts until my pt ran outta stam. It was killed but I escaped and then a second rhyio came along so I shot it with tranq dart. It started running only after a few shots (weird) and then I fell off a cliff and freakin died. At least I now know where rhyio spawn🫥😭🫠
