Also, according to the work being done
here, DET is more important than we've been giving it credit for. I've tested this formula against in-game numbers and found it to be accurate. I've also messed around with stat weight calculations, and came up with some unexpected results.
The weight of WD and CRT scale up with INT and DET.
The weight of CRT scales down as CRT goes up.
Because of how everything is itemized though, this only changes 1 item in our set.. the head item goes from Summoner's Horn (noooooooooo) to Allagan Circlet of Casting.
