Just fyi for the AF body Cover enhancement, you don't need your target to be within 8 yalms to get the MP back. You just need the actual status effect "Cover" active to get MP. Beyond this, while it takes 8 yalms for cover to work, you can use it on someone from further than 8 yalms.
So if you simply want to use cover as a mini-Sanguine Rite, you just need someone within around Provoke range to use cover on.
