Guild combinations for crafting?

[Killua]

What are some of the better guild combinations?

Such as Fishing + Cooking is a good combo :D

[Evaporater]

smithing + goldsmith is one ^^
also alchemy seems to be needed somewhere in all guilds, so u should level that up too :p

If you're really interested in making a robust selection of arms, armaments, and items, you'll need to raise all your skills except cooking up to 60. No, I'm not joking.
