Xp Set?

I'm level 64 Right now, and leveling up is taking quite a while. I know the best places to grind, BUT I recently realized that having an XP Bonus set of armor, accessories, etc would be helpful and make things a lot easier. Do you guys have any suggestions on what sort of pieces that would entail?

 

Upgraded Orc Mask (A Fighting Species, iirc) 26% / Blueberry 21% (if your Orc Mask gets 20% or less xp bonus)
Matryoshka Shell 26% (hidden boss near the Iboju Village)
Greaves of Honor (Iron Heart part II) 39%
Bad wolf 42%

Rarity 15%
Rarity 15%
Laen's Curiosity 10%
Hexed Amulet 21%

and a Joyous bow 33%, it's from a merchant, don't know which one. Olux/Troms weapon merchant most likely.

 

^^ Sage for mage, Glowstone Killer for warrior, Sapphire Shard for assassin

 

Thank you, this is really helpful! Though, which one of these are mob drops and which arent?

 

Bad Wolf is mobs/chest. Accessories are T3 and T4 chests, and Joyous is from Craftsmas Island. Everything else is quest rewards or Matryoshka Idol slaying.
