Cross Skills I should get for GSM

[NJA]

I've raised Culinarian to 50, Weaver to now 39, Alchemist to 20 and GSM to 25 (on another character this one) and there are a few X-Skills I find are extremely valuable, see linked picture. Text is too long for it to be post on those forums (stupid character limit).

Thanks! That's a really interesting read and I'll take it on board when planning my next moves.
