For Intelligence you have to keep in mind some important things that make it very powerful
Staves have a weapon art to buff casting, worth it if you know it will make a difference

Free-aiming helps a lot
If you want to rush Oceiros you should invest into some reliable Raw weapon that you know you'll end up buffing with Crystal Weapon. Those would be Handaxe, Mace and Falchion, all great options for a minimum stats Sorcerer because they have high base damage.
Shortsword is a great no stats straight sword to infuse with Crystal because it gets S scaling
