How is an easy way to kill the rathos?

I personaly like the Poison Battleaxe which you get from upgrading a hunters knife alot You will need alot of materials from a gypceros like rubbery hide and poison sacs. Go to the jungle in a gathering quest and go to area two, there you will find a beehive and if you press O near it you will collect honey and combine it with a potion to make a mega potion( continue this until you get 10). Usually the old woman will sell ivy and if you can buy some then buy as many as you can. Then buy some spiderwebs from the other peddler and combine the ivy with a spiderweb to make a net. Buy a trap tool then combine it with the net. Next go to the village chief and do the mission the formidable velicidome(a 2 star mission) and get the flash bombs and kill the velicidome( don't used the flash bombs against it). It will let you keep the flash bombs. Now you are ready to fight the rathalos. As soon as you see it throw a paintball at it. Throw a flash bomb at it's face and it will become dazed. Only slash it in the face and continue it until you run out of flash bombs. When he runs at you, dodge it by running and pressing X away from it. Only attack him when he shoots a fireball and when he does, go around him and keep on slashing him in the face until he eventually dies.
