47-48...

I did have one maximillian(sp?), one masumune, and Bubble/Bravery/Faith spells. The rest was storebought in shops along the way that you normally had access to.

I guess information about the boss strategy could be a spoiler...
(SPOILER)
Without shellga and bubble, the final boss could have been very hard at that HP level... but with 6000hp after bubble and shell reducing the attacks to 1000-2900 range depending on the attack... it wasn't too bad... -aga are 800-1300 range.. and when he's in faith and used magic shield before dispel landed.. he hit a few other spells upwards of 2500 group.. Holy hit for 2500~ single, and his final attacks started to climb towards 3000 group, but never broke it.. not sure if shell might have dropped.
