So even if something is worth something, always be on the lookout for making trades where you come out on top or make profit, over time it will add up.There are multiple avenues to find a Trade Partner: Trade Lobby Channels But I guess that person really just wanted some necro summon GCs quick, even plain ones, and didn’t have a problem overpaying for them. Then again, different people are different, and sometimes it pays to be patient and wait for “desperation” like I just got 2xIst runes for 2xplain Necro Summon GCs, which classically/historically I’m pretty sure would only go for Um or Pul.

While again this “1.5x the previous” doesn’t apply for some cases, it’s what I use personally for a general idea. Mal+Um probably goes for Ist, though Ist is so commonly used as the “base” currency for HRs that I imagine at a certain point you could probably just trade Mal for Ist straight up as Mal is a useful rune to have for many powerful runewords. Mal will be Um+Pul, again instead of 2xUm, since 2xUm gives you a Mal anyway it would be pointless to trade that way. In general the next rune up is 1.5x the previous rune, there are a few exceptions such as Cham not being worth nearly as much as Jah, Jah being worth roughly the same as Ber, Sur being worth roughly the same as Lo, but for the most part, if you want an Um, it’s going to cost Pul + Lem (2xPul will simply create an Um, but for trading diversity of currency is valuable in itself, so it’s only 1.5x the previous rune).
