My advice? Spend a few hours leveling a job with Sanguine Blade so you can use that. Paladin or Blue Mage should do, and you can double BLU as a proc mule if you decide to get those spells later.

Alternatively, finish a WoE gun and level COR. Honestly, the former will probably require less overall effort than brewing with one of those jobs (Assuming you're doing 1 at a time), and the latter will come in handy for pretty much anything you want to brew.
