Here you may upgrade your weapons and exchange your shards and stones. Afterwards, you will be required to edit your profile. This can be done at any time during the week. The current exchange rate is as follows...
500Gp for one Shard
5 Shards for a Stone
2 Stones for a Crystal
1 Crystal
Elemental Attack Shards do not count as the shards here, though you do have a limit of 5 per slot. These shards can not be bought here and must be obtained some other way.
