How to achieve "Elemental Mastery"?

[Masciferator]

Trying to get this enhancement at the trainer in GHD. It says "complete the 6 Elemental Masteries".
It's not clear to me if this refers to production or consumption and, also, if this can be achieved by the party (ie several characters generating / consuming different elements) or if it has to be a single character.
Any help appreciated!
Cheers,

It means you have to get the 6 elements as enchantment options, you just have to generate the elements several time, (to get their respective element enchantment)

Previous answer seems to be correct, but maybe too brief. In GM mode, at least, each elemental mastery requires generating ("infusing") the element a certain number of times and anyone can do it. (I imagine that infusing an element that's already infused might not count. I didn't pay attention.) Once the cumulative count is reached, you get the Mastery achievement for that element. Once you do this for the Six elements, you get the ELemental Mastery achievement.

As you get a Mastery, that element becomes available as an enhancement. The ELemental Mastery is an enhancement that lets you choose each time rather than being stuck with one. (Got the achievement, haven't enhanced anything with it yet, but there are other effects that at the end of your turn let you infuse anything and it gives you a pop-up menu at the end of your turn where you pick.

Is it enough to generate the element? Or do you have to actually use it? It's been a while since I played guildmaster.

Anyway, yeah, that's the gist. Make and use an element enough times and you gain mastery of it (and get granted the ability to enhance cards to produce it). Do it for all six elements, and you get given the ability to enhance cards with "any element" generation.

Many thanks all, great answers. I'm playing in GM mode indeed.
