Hmm yeah I see. Bah. Sounds like something too costly to do before we have anything working though :\
I was looking at Flash Farner
I only crafted one mythical and it became just empty with the mythical skill only. Didn’t add anything yet because it’s Hunter and I switch to click on the Shrine and back to my ring.
How do we go about to craft Insolence of Strength for example?
- Find the item with Defiance Set
- Use Emerald to max the item quality (then item level…? Or just one of these needed? Not sure why we would want to increase item level, I think item quality dictates possible stats and item level the level at which we can equip it)
- Remove all affixes but the set with Kyanite
- Use 5 rubies and Larimars or Sapphires until we get the exact affix combination we want
- Use Diamonds and Fluorites until we get the very maximum value for each affix
Supposing I’m right, I’m guessing if I farm 24/7 for the next 7 years I might be able to get that one item done. Then I will need the other 5 items.
I’m not too far off, am I? 
As to the issue you described, I can think nothing but the MP reduce % affix.
If I read it correctly, max value is 40% for the epic version. If you happen to have at least 2 distinct items for those 5 slots then you can have 2 * 40% reduce. For 3 items you never need MP. Even 80% reduced MP on 2 items seems too good to be true though, either there’s a hard cap below that or I’m wrong somewhere… again.
Edit: and I guess Cognition of Strength is a Mythic item that was added a set affix to it? If I remember correctly the +2 to all sets is a Mythic only skill Nevermind, Elixer. Regardless, it looks like I have to farm a few months/years to have a half decent farming build in order to start farming for the en goalds/builds/tests. Didn’t expect that from a mobile game! Let the game start
