Not to mention other equips. Just sold a Mana Cradle for 400 mill, that I bought a few weeks ago for only around 100 mill.
Basically this new star system let's you run amok with enhancements because instead of outright destroying it, it gives you this equipment trace coupon thingy, meaning if it blows up you can restore the original weapon, all its stats, potentials and nebs onto a clean one... which means suddenly everyone is now buying equips up left and right to meet the sudden new demand! So buy now... buy everything that's cheap now! Srsly, if you have any mesos at all I would just buy up every last Fafnir weapon you can get ahold of! o_O
