^ Currently the most recent messages from global on Xyr. I'd talk to Aramidis about how much it'd cost to buy goods. Once you know that ask if you can put those FPs onto their arc (lvl 35). You could ask Mindlessforge as well what their prices are, but with their arc already lvl 97 you'd need to find out whether they intend to lvl it any further
Well, that screenshot is from November. According to guildies shopping for Arc sets, going price (including mindlessforge) is 500 fp, but some sellers are asking higher, including one asking for 650. I bought mine in December for 600 fp. Both mindlessforge and citizen10 are highly regarded and have done numerous trades with people in my guild.
