Guild Wars 2

I have a doubt about getting the Superior Rune of Lyssa. It´s possible to craft this Rune? I see it in the TP for about a litlle more of 3 gold each, but dont see how to get the rune without buying it.
I want to aplly the rune to to my armour, but dont have the gold to buy the 6 pieces so i spent some karma to buy the cultural armour with the objective to salvage the runes for my personal armour. The problem is that i am unable to salvage the cultural armour with the BL salvage kit (or with other salvage kit). So how people are getting this runes?
I see some people using this rune with their personal armour, so there must be a way to get them.

from salvage ofc.

The stuff with those runes drop sometimes but there is a trick to it. You get gren/yellow runes of lyssa puth 4 of them into MF and you have higher tier rune. Sometimes you get exotic drop with one of those so another salvage.

Thanks. Didn´t know that about the mystic forge. It´s a slow process but i think its better than waste about 20 gold in the TP.
Thanks.

MF is nice but with runes you sometimes get some random rune so watch out
