A must have tame. A pretty much end-game tame. This beast itself is a symbol of strength. If you want one, look for the highest one. Pay attention to giga that's at least above lvl 100 (if max level capped at 150) don't waste your time and energy on giga lower than 90.

Tame this beast only after you have enough eggs to make 10 exceptional kibbles and have a bunch(about 3-4ish) of 140%+ damage crossbows ( there is a chance you will get rewarded of them after defeating the alpha variant of carnivores).

A lot of preparations you have to consider before start shooting tranq arrows on it

You gotta cage the giga within 4 METAL dino gateways. Luring them in is not much of a problem. After you done it, next:

I recommended bring about 4 crossbows that are 140+% in damage to shorten the taming time.

Prepare around 500-600 tranq arrows close to the taming site.

Bring your exceptional kibble.

Prepare about 300 narcoberries if you are using exceptional kibbles, bring a lot of narcotics if you are taming it with prime meats.

Clear all the predators around you in that region so you can shoot the giga with no disturbance.

Have enough food and water ready to get you full before shooting

Start shooting the giga on its head at 04:00 a.m.

Shooting at the dark only makes it a lot harder and risky
