stone of change and crafted items

[mlpatton1]

I created several items that were ml 5 then went to bind and attune them on stone of change. used 400 fragments instead of the 25 that should have been used. is this an error or is this a feature/penalty?

Would guess it's an error because the crafted items have a variable ML.
And if it worked you could cheat it by placing in an item with only the prefix or suffix so it has a low ml, attuning it and then finishing it, increasing the ML.

There was an issue similar to this with the hats from Crystal Cove:

Since the item originally had no ml, even after upgrading it to a certain ml, the stone of change still considers it a no ml item.

Same thing is probably happening here. Since, after removing all the effects from the item, it was no ml, even after upgrading it it still counts as no ml.

In case you didn't know, no ml items require 400 shards to attune.
