First, you only need 4 levels to max out the craft as far as making things. You will also gain significant levels if you use Runes you have not used before, so if there are any you don't know, make a Glyph. If your Extraction is high enough, you get most back. But if you have not used some potencies and aspects and essences, use them first to learn them and then see how far you get from just that.

It would also be effective to go out and farm undead mobs as they drop lots of Glyphs. Zombies and Bloodfiends are squishy, so they are an easy mark.

Yea but the fastest way is to Decon player made glyphs, same as trading daggers

Its not that much faster. It's only a little faster. Back before they buffed the Inspiration from decon, the difference was huge, now, it's not worth the friction of swapping these between players.

You can do pretty the same thing by swapping between alt characters on your account and get the same inspiration as swapping with other players.
