To exploit Rathian's weakness to the Dragon element, use weapons or attacks with Dragon properties. For example, a dragon - element sword or a special move with dragon damage.
Rathian is also relatively vulnerable to attacks on its head. Hunters should aim for this area when possible to deal more damage. Additionally, it has a weakness to certain status effects like poison, which can gradually deplete its health over time.
In Monster Hunter Stories, the Pink Rathian is vulnerable in multiple aspects. The Thunder element is its main weakness. If you're using a weapon like a Thunder - based sword or bow, you'll see more damage output. Another important point is that its wings can also be a weak area when it comes to certain attacks. You can try to focus your attacks on its wings when it's flying or getting ready to take off. And don't forget about the head, which is a classic weak point for many monsters in the game. By exploiting these weaknesses, you can have a better chance at defeating the Pink Rathian.
