Any idea what the value might be?
cheapest crafting costs at this moment say about 550k, maybe a bit more.
You already need 123 HM (99 for 33 Blade Shard, 12 for 6 Oil, and 12 for 6 Handle).
Complete Crafting Mats:
2 x Wood of Glasir
2 x Black Steel
33 x Blade Shard
6 x Handle
6 x Oil
2 x Silk
I hope that will help you a little bit.
