I will work on getting the marbles needed for the runes I am missing and then it is just a case of hoping for the double xp rune to drop.
I have a maze setup that will drop around 24 marbles a run, I just run it with a low lvl mule and my main to get marbles.
Once people are ready we can start doing runs, it would be handy to have a cor for the extra xp roll, but on a bird run anything with piercing weapons is good.
I havent found much info so far on the new NM runs which are like a progression where you move onto harder NM's, but I will keep searching for any info on drops etc.
