i have 6 remedys, 6 malboro tentacles, and 6 steel pipes. when i click on the ring it says
"Can't Summon GF"
i dont understand this. i have all the items. what do i have to do to operate the ring?

you need remedy+

use alexander's med level up to refine remedies in remedy+s

6 Remedy+ using Med Lev Up from GF Alexander (you need 60 Remedy)
6 Steel Pipe
6 Malboro Tentacle

this will make your Ring work
