I have a build similar to yours but mine is Cleric 1 > Priest 3 > Pard 1 > Oracle 1 > Pard 2 going to Inquisitor.
I find it funny, specially with oracle AoE def field and mdef buff, lack damage, it is heavily dependent on gear upgrades (mostly weapons), and Change make things interesting also, sometimes i get an event spider that drop a cube, so far only got repair kits and high cond. pots from it, but i wonder if something nice drop from it.
Since i got bored of the game i left it selling buffs at klaipeda, unfortunately, i sell bless cheap because the damage from the buff come from the buyer SPR, not from the seller (us), so if someone with basic SPR buy bless from the shop it will only be a small amount of damage (i think it is 83 with all attributes maxed).
