I suggest you get that bow of yours and kill Bandit Archers. With PT and Skill GT you get 1SP per kill and its really nice. You don't need SOS armour unless you really get owned by archer. I had full SOM/Sun gear and I never used a HP pot.
Why bandit archers? Because with SOS(+5) bow you can just use imbue and then Ctrl+Click on archers and you 2hit them. So 2 hits - 1SP. You don't have to move at all. The spawn rate is so good that you basically just find an archer click it and then click another and another and another til you have to go back to town.
Do it til you are lvl 18. Then go delevel back to 16. If you get lvl 19 the Skill XP rate that you get will lower too much.
Also good way is to just kill bandits with imbue and your SOM glavie, you can 3 hit them or so. Maybe more. I saw a lvl 16 SoSun glavier 3hiting regular Bandits with 9 gap.
Anyway, I don't want to farm unless I have GT and Skill GT because you do it 3x faster then.
I don't know what more to say. Go read that guide and ask if you don't understand anything.
