My artificer is level 20. I want to put Electrical Absorption shard onto Glorious Obscenity. Electrical Absorption is a +3 shard, so it adds 6 levels to the item's ML. Glorious Obscenity is ML 17. OTOH, Cannith crafted items never exceed ML 20 regardless of the shards value. So if I do that, will my Glorious Obscenity be ML 20 or 23?
