Hope you like arenas.
The best way to do it is to get the
Felyne Hairband from the G rank arenas - that means Apex Deviljho and others.
I didn't know about this, and I don't even have the G arenas I need unlocked. So instead I used a 3 slot chest (any will do, hell I use Chakra), 3 Charmer gems and a crappy charmer talisman. Every other slot was torso up, and I had to do arenas to make the black belt gloves. If you have a better charmer talisman you can get away without one torso up piece - I found a +6 one while farming which enabled me to swap out one armor piece and get speed gather on the set.
I'd definitely like to make some progress on G arenas. Glorious maid armor. I had fun doing the normal ones too, frenzy normal/black gravios is hilarious chaos.
