Well, i am finding myself looking to build a relic "kikoku" im going to farm the coins myself but if someone wants to sell them to me for cheap please send me a PM. also can trade them for crafted items(104 cloth craft) please let me know :)
also, ive been hearing that SE is planning or is in talks about making the relics upgradable or augmented in the furute. it makes sense because all the hard work taking them up and having the new weapons beat it seems not cool.
