I saw a giga and a tyna (idk why the tyna isn't on dododex) on the green obelisk mountain just go to the top edge of the green obelisk island. but it might not have one. Also there's a explorer note on the mountain
I killed a level 150 giga on the center with 5 rexes that all had about 40k health and between 700-1400% melee damage and 100% imprint. Only the rex I was riding had a saddle. Nobody died, and they each had about half of their health left.
You can kill it, you just need to be very prepared.
Oh so you want to kill it. It’s one of the most powerful wild creatures in ark. It has tons of health, hits like a MONSTER TRUCK, and easily murders everything. Oh how do you kill it then? Easy. Just lead it into water. Gigas can’t swim so it’ll just drown
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.
