Blademaster Guide:
Before Starting a Rathian Mission be sure to have:

Honey
Mega Potions
Well Cooked Steak
Flash Bombs

At the start Take all the equipment you need out of the blue chest, go to the central point of the map and use a phychoserum, once you have found the Rathian, use a flash bomb on her, if need be use a paintball to track her, start to hack always at her head if able or her tail first, try to cut off the tail so it doesn't get in the way, once the tail is cut off keep flash bombing and attacks, repeat this until dead, if you run out of flash bombs make sure to combine flash bugs with bomb materials, you will get 3 carves from the Rathian and 1-2 carves from the tail, congratulations.
