I was flying to the mountain close to the volcano called the frozen tooth, I was needing metal, just chillin, when I spot this giga while I'm on my level 111 argue, I panic then realize it's probably a low level cause the bigger they are the less likely they are to have a high level. I should've bought a lottery ticket that day cause my spyglass told me it was level 120! Yes a frickin level 120 spawned on my mountain. What fun.
If one is encountered near water, you can simply lure it out to sea with a flyer and it will swiftly drown. Given the water is deep enough. If encountered inland not near water. Pray to the overseers you have something fast enough to out run it. Then promptly die because they're as fast as a mad Hispanic mother with a shoe. Not as deadly as one though.
