Crafting
yeah finding new recipes give you the most xp in crafting. If you really want to lvl your crafting. Search for a guide. If you want to it without a guide i shall tell you this :-).
you need to craft new armor that you don’t have in your recipe list yet.
what does it take to ‘find’ those recipes?
make the 2 pieces of armor for the same armor piece. ( i cannot remember the names. But you always need to make 2 things for gauntlet’s or 2 things for a chest piece.) and make 1 insignia. go to the discovery panel and throw in those 2 things frome the armor and the insignia and you should have that piece of armor with the stats of the insignia
Honestly, I wouldn’t just experiment with the crafting to gain exp. I’d use a guide, as valheru suggested above. Gw2crafts has great guides that are cost-efficient.
TBH using the discovery tab/process is actually pretty easy and a good way to lvl up crafts. I have almost all crafts at 500 which can go to 500 all just from the discovery panel and gathering everything myself.
The secret is once you figure out a recipe it is very simple to figure out the rest as they all follow the same pattern. Either 3, 8 or 15 of a certain fine mat, the 2 components such as say a shaft and axe head or spearhead etc. Every weapon/piece of armour all have the same stat combos available so it’s pretty easy to figure them all out each tier you go up.
Hope that makes sense.
