Best for xp tip:trap a titanosaur and shoot it continuously until death ( btw you need 300–450 ammo)

If you play on casual and on any difficulty crafting it gives 450 exp which can be used for farming exp

And then u can just break it a and make it again because in casual mode you get all material back after breaking any structure

Like up so world could know

In pve they are only usefull for rhyniognatha and tropeognathus taming. Otherwise it's really a waste of time and resources.
