I have got 5 adamant armor and it was pretty easy actually. I am playing the PSP CC if that helps. Anyways it went from 1 pink tail every 3-4 hours to no pink tail in 10 hours. I have a bunch of sirens so I use 99 and if unsuccessful I reset and try my odds again. I want to move on and get the crystal rings from the red dragons or ribbons for the rest of my crew. I may even do the cursed ring deal too.
So with all the secret summons and 5 adamant armors I am in good shape. My only concern is that there may be a limit on how many pink tails are dropped now. I have like 600 more sirens so thats no big deal. I'm sure I can farm red dragons with ease. I did sit for days randomly fighting MindFlayer without them. That's in another thread though
If you were going to equip all your characters with what ever you could what would you put on them. My set up would be like this:
Best weapon of course
Shield or no shield... depends on character.
Ribbon
Adamant Armor
Cursed Ring/crystal ring
If I go with the cursed ring I will not only be immune to status effects cause of the ribbon, I will absorb all elements as well. The only thing that could hurt me is physical attacks.
