Yeah that is still kinda a lot for one companion. I think I sold a full companion set for 140 runes or so a while back, but it all depends on the other person's value of runes.
Grr I need to find more of this month's rune donation items. Nommy bought all of them off of someone who was selling and I'm not sure if they would be willing to sell one of each to me :c The person hasn't replied in their selling thread yet. I think they are quitting but I am not sure. Too many people are leaving/on hiatus lately.
