Do you ever actually post peoples ISO’s or just looking to get +1s?
Strictly speaking, you could start with a 4OS eth glitched sacred armor (1350ish defense), socket it with one perfect or flawless ruby (depending on wether you prefer crystal red or dark red), 2x puls (to get 2160ish defense) and one zod, and be on your merry way, all for about 100-200 Paul currencies.
Strictly speaking (again), this should satisfy your armor ISO, but make no mistake, this is just a +1.
Now I know what you're thinking, RJ: it wouldn't self repair, but hey, it would neither break nor lose durability. If this isn't a win/win (and a fairly long +1 as these things go), I sure as shit don't know what is.
Buenos días
