Advanced elixirs questions

1. What is the recipe for getting a B grade (not sox) elixir?
2. Do advanced elixirs make the item immortal?

Hey, you can get advanced Elixir by desytroying full blue Items +5 or higher, the better the blues and pluses, the higher the chance to get advance Elixir A or B (B is much rarer).
And no, advanced Elixirs just add (+1 or +2) to your current plus, means you can go up to +6 or +7 without worrying to destroy your Item.

Thanks,

The last info I knew is that you must have +7 fb to get a B grade.

The immortal info got to me from some guy on the server, didn't believe it so I had to ask.

A simple question:

Can i use an advanced elixirs higher lvl on a lower lvl item ?

I mean using a lvl 9 adv. Elix. on a lvl 52 Bow for example. Or do i have to get a lvl 7 adv. elix. ?
