So long as you don’t get bitten roughly 3-4 times, a titanoboa or other tranquilizer creatures can’t do much against you. They inflict torpor(roughly 40 torpor per hit), which leaves you prone to attack from stronger creatures or swarms. So long as you keep your distance(titanoboas are easy to detect with their movement audio).
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?
