I'm just minding my own business and land on the mountain closest to death island on a Pteranodon and out of the gloom is a pack of sabers and after they finish off my bud they get killed by gigs and I get killed by gigs and don't even try to get my stuff back. Very deadly you need many shocking tranquilizer darts if you wanna live
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.
I spent an hour taming a Max lvl anky on a ledge. After about 20 minutes I looked down and 2 gigas were below looking right at me their heads almost reaching the top of the ledge. They stayed there the entire time
