..... errr right, 2 x ist = one vex, and you do know that ist and vex cosider to be mid high rune right?

The order of runes go as this... if you don't know:

Ist
Gul
Vex
Ohm
Lo
Sur
Ber
Jah
Cham
Zod


You want to get jah, ber or ohm... bring couple more ists...

But ist should beable to get you a good gear.
