The best current use for the titanboa is for raiding. Take your tamed argenvatvis, find a titanboa, pick up the titanboa using LT while riding your argenvatavis, fly to an enemy base. While flying over an enemy base press LT once again. The titanboa will then drop. It will kill any player or creature in their base that is not in a building.
I think the titanoboa is one of the best examples of imbalance in this game. It essentially serves the same purpose as a scorpion except it does more torpor. It is also much harder to tame, requiring multiple FERTILE eggs to tame, even if you have the more powerful dino eggs it can take a butt ton to tame just one. Why would you do that when you can use those fertile eggs to raise up the powerhouses and just go on to tame a few scorps. You can also ride the scorpion and its pretty good at climbing, abd they only require spoiled meat and tranqing, its super easy to tame and they do the exact same thing. Some people tame it just for its kibble, look if you're taming speed is low enough to truly warrant kibble, its still not worth it. Because you would need to sacrifice even more fertile eggs to tame just one. Also scorpion kibble is good for rexes, its a good kibble to have! If it had more abilities it might be worth it. Couldn't it have the ability to be a giant bola to stun large dinos
While you can't tame them you can make them do your dirty work for you, getting that edge on the raid pick up with an argentavis and drop one or multiple into an enemy base voila Dino's are dead and you can run in
Since you can't tame them it seems hard to get titanoboa eggs. However, you just have to build a small pen with open roof, get your argent/quetzal and drop some titanoboas in there. Since they won't despawn, you have an infinite source of kibble!!
Don't tame them, its not worth it. They still have their uses though. They're a good source of prime meat and hide, aswell as loot. And you could always use the good ol' tactic of dropping them into enemy bases with argents. I could see this being a good way to lead a raid as they are pretty quiet, they could take some people by surprise, and could weaken or knock out some enemies. And if you really want their eggs, do what people did before and make a special pen. It would probably be more worthwhile as a tame if it had some other abilities or if it took regular eggs instead of only fertile ones. As a tame now, it's just a less versatile scorpion with higher torpor damage. And scorps are easy to tame. Just tame some scorps and save your babies. They're more of a novelty tame now, sonething thats pretty cool but doesn't have much real use.
