The dossier says:
"Found only in the dark caves of the island"
They are already wrong! It should say something more like:
"Found everywhere but the dark caves of the island, this creature will gladly ruin your day by jumping out and killing you as soon as you even think about going to the swamp. Nearly impossible to tame because it has to be tamed via passive which is very difficult to do. Worst of all you need to feed them fertilized eggs. Why can't it e a little easier? Up-vote of you agree!
If u are in ark mobile ( like me ) and u want to get titnboa eggs make a small room without a floor pick a female with an argy and drop it in the room and get the eggs (sorry if there was any grammar mistakes)
You tame them by droping ferti eggs from your inv on the ground. You need to do so when the snake is not aggroed, so sit on a rex or smthing it wont attack. Be sure to drop them from your inventory, not from dino ones, that will make it bugged, it wont eat. To a lvl 20 Rex egg gives 29% on 2x event, bronto 26.7% and giga and wyvern the same, looks like all the big eggs give approxymately the same amount.. so dont waste the best you have ? If they get aggroed on you just run away and return, taming wont drop. Happy taming!
These guys are super scary. no matter how powerful you are, always watch out for these guys if you're in or around a swamp. swamps are FILLED with these guys, and when they bite you, they fill your torpor bar up and knock out both you and your mount. DO NOT get knocked out, especially when in a dangerous area like a swamp. if you get bitten, eat a bunch of stimberries and feed them to your mount too. my pteranodon and tapejara and me can take out almost anything we come across (so far), and i'm still terrified of these guys. stay away from titanoboas and other poisonous creatures, even if they're not powerful they'll get you killed. keep at least 50, preferably 100-200 stimberries on you when traveling through, over or near swamps.
-Build a trap wooden, 3x3, 3 walls high (with entrance ramps if pve) just out side of swamp.
-Drop or lure Titanoboa inside.
-Fly up untill out of render distance to stop agro
-Fly back down, hover above (not too close)
-Drop eggs 2 - 3 at a time from your inventory not tames.
