Rage over Sophia

[SpookyGhost]

As someone else said, Sophia's difficulty is somewhat similar to A9S.

Since OP is a DRK I'd say A9S is far easier than Sophia EX. :P

e: Also I'm not sure if this has been covered but are you using RF or PF? I used PF for my Sophia clear and it worked out a lot better - being able to ram your head against it even after the lockout ends is really useful. Even if the group falls apart you can try and keep the good players around for another go and just refill in PF until the clear happens. Just make sure you specify it's a clear party since, from the sounds of it, you've got the fight down by now.
