I havent done much unbound crafting until recently when my Arti got up to lvl 90 in all schools. So tonight, I grabbed a base ring, disjuncted it and prepared it for crafting, made an unbound underwater action shard and an unbound swim +10 shard. After applying a shard of potential +6 then +7, I crafted the ring which became BTC on equip. I was under the assumption that crafting unboud shards were to be used so that you can make unbound items. And no, the ring was not originally a BTA item. Thx in advance.
