Well, try finding a CTHO party and be a Magic Strings slave or west orc village party and Double Strafe spam high orcs.
Other than that you'd be stuck fly winging and spamming Double Strafe at Porcellios.
Alternatively, I'd recommend re-doing your Bard, it'll only take 30 min to job 50 as Archer.
Pure DEX to 60 then pure INT to 50 (if that is within the total INT amount you would get as Bard, combined with Sohee Card Shoes you will have infinite SP as second class)
DS 9, Vult 10, Imp 10, Owl 10, AS 10 in that order.
At level 12 with fire arrows straight to wolves until base 26-30, spam the free Novice Red Potions.
Then straight to Porcellios (if you can get a Gakkung Bow) fly wing and double strafe 1 hitting them to job 50. (At the start you might need to DS and then one normal attack)
You will not run out of SP as everytime it gets low you will level up.
Max. time to get job 50 is 30 minutes from level 12.
Job change to Bard and then back to Porcellios, you can stay there with DS up until base level 70 then you can head to Juperos with Arrow Shower.
It'll be faster than trying to level without AS 10, trust me, unless you are fine with spending 10 second class skill points into Arrow Shower.
