AF Coffer QuestionFollow

So pld is ready to go for his first coffer af. i get the eldimene necropolis coffer key. I talk to Guslam in upper jeuno and he tells me i need to go to the boyhoda tree. I figure this must be left over from my 54 drg which has 2 pieces of af gear. But its the same quest for everyone class the bozharetz gaunlets or wahtever, go find the coffer in eldiemne and what do i get a damn vital elixar +1. Do i have to do the coffer AFs for Dragoon so i can do them for my pld please tell me no. Also anyone willing to help me get the coffer key again for necropolis please let me know

Thanks ill probably just complete the hands quest for my drg but do you know the name of the npc to reset this quest and where he/she can be found
