This was a looted hat that I am experimenting with so I can learn more about swapping and adding properties and intensity. Original item intensity showed 478 Step 1) I attempted to add Lower Mana Cost, thinking that it would replace Self Repair 3, but it was not allowed (I'm guessing this is because the 478 intensity?) Step 2) I raised the LRC from 11 to 18 to remove the Self Repair 3 Step 3) I then raised Mana Increase from 2 to 7 at this point item intensity was 459 (I probably made a mistake raising things first, but I am new at this and this is experimenting) Step 4) I lowered LRC from 18 to 1 to lower the intensity below 450 I have tried to add Lower Mana Cost, but it tells me that I cannot and the item is still showing 5/5 properties. Can you no longer actually remove the Self Repair property? (I did a search and came up with a post showing you could and that a new property would take it's place) I am so confused now and any help is greatly appreciated Disclaimer: At no time were any feathered hats harmed or killed during my experiments. I have verification of signed waivers by feathered hats authorizing any and all experimentation.
