well before they changed the cap from 100% to 50% i would have suggested you get a cap at lvl 18, put on the lvl 20-22 gear set and upgrade each piece to +4 or higher but +4 is good enough. carry about 100 small hp potions, and kill strictly ghouls and mummys. now most people will say to cap at 17 cause ghouls will give more which is correct however at lvl 18, mummies give more sp per kill than ghouls. i suggest killing these untill you have about 20,000 skill points...with no buffs that will be about 45,000 kills
with a +4 set and a +10 or higher titan event weapon, ghouls and mummies die within 4 hits. i also suggest you get some cheap hit rate acc if you cant affor a tok.
these just the way i do it and just a suggestion. this is what works for me
