to get heavenly scales easier, you must be HR9 and do the great arena quest with the silver rathalos and golden rathian. i forgot the title of the quest but you can be sure to farm heavenly scales much easier on that quest. if you cant tackle both, do the silver rathalos quest in the tower, that's on G rank gathering hall. make sure you capture the monster, break all the breakables and cut off the tail.
yeah.. easier said than done. :oops:
