that what me and my friend are saying, this is his perdicament, he found archid traded it for 3 ums, now he is trying to trade 2 ums 4 ist, so he makes a game and people join and they start asking him if he has a ber or a vex for thier ist rune...
well they r stupid, if u have lots of patients and a good rusher, just do hell forge rushes, and around every 5 runs u should get an ist, thats how i get most of my runes.
