Well, if 0 Native, 20 Hit is worth 70, then I'm guessing that 30% Native on Excal is more valuable than missing 5% Hit. (The existence of POSS makes the absence of hit not a huge deal for HUs). Girth said he values it at one stack (this was just us talking about it after I found it).
Any other thoughts? I'm thinking about auctioning this but I don't want to do poorly. Thanks in advance for any input, and thanks for all input that has been given thus far.
