This is a good armor set for treasure quests but you need to be HR4 or higher to be able to get the materials.

weapon -- any that has at least 1 slot(but 3 is alot better) + Blessing jewel,(2x Gathering jewel)

helmet -- Chain helm U + 2x Backpacker jewel, Blessing jewel

plate -- Chain mail U + 2x Gathering jewel

gauntlets -- Chain vambraces U + 2x Gathering jewel

waist -- hide belt

leggings -- Rathian HeartGreaves + 2x Gathering jewel

what this gives you are the skills:

--Divine whim -- alot less chance of items breaking when used (e.g. pickaxe, bugnet, flute)

--Gathering +2 (or +1 if you weapon only has one slot) -- increases the amount of things you get from gathering

--High Speed gathering -- increases speed of gathering and carving

--Backpacking -- allows you to carry egg-like items faster and you may not drop it from recieving small attacks (e.g. vespiod sting)
