Merge of Usable items feature and enchanted stones

[Jubaris]

I was thinking of a nice way how to integrate spells further.

How about being able to merge an enchanted stone with one of your usable items? In that case, your usable item can cast the 3 casts of the spell of the enchanted stone, instead of giving it to your profile.
Also, that the items have some kind of trigger on how much was one type of enchanted stone used on that item, so that eventually, the item becomes able to cast it without enchanted stone, on low basis (1 or 2 casts per spell recharge).
