Also, was edited into the previous but after you posted by accident, so--
It was mentioned in the helovia chat that in the past certain offensive or defensive items have counted as more than +1 to the DI or OI stat. How is this determined, by adding +.5 for upgrade to the item, or only if the upgrade is something offensive or defense? Is there still a max of 2 for the OI and DI stat, or can it go above that if you have, for example, two DI items that are fully upgraded and +2? This also confused me because it says on the stats page that items are +1 each with a max of +2 total, and that one item cannot count for both of that +2, which combined of no mention with items being above +1 made me think +1 was the cap.
