Geo build

I'm just currious about build stat (MONK THROW USER).
My friend told me that Monk can do 300k damage to Raaton 2 with geobreaker skill.
What do you think about this build ?

1. INT>CRIT>VIT (int max - crit max - rest on vit)

2. INT>DEX>VIT (int max - dex max - rest on vit)

3. INT>VIT>DEX=CRIT (int max - rest on vit - dex & crit raise together, it means about a half that we can max dex/crit)

about LINE APOSTOLIA : using 6 purple line with 2 red line (for crit rate, ASPD, autoskill, with extra 2 red line for HP and DEF).

weapon using THROWING.

Which one that can give highest damage ?
Is there anybody who tried this build ? and what do you think ?
Thanks for your answer and sorry for too much asking.

note : oh i forget something, why i increase VIT ? its for survivability (HP, DEF, add a little MDEF) and also i know the weakness is about evade and aspd.
