you should have applied it to an account with decent stats... but anyways i would start off doing pure quests if you want to stay a pure and try training some p2p skills like hunter
go to rock crabs and train it
or do pure quests so you dont need to train
if you had an ok account i would have said go to monks or fleshies make some quick cash off the herbs, the merch, then buy goods for leveling your stats.
Well, i finally bought rs mem after 3-4 years of f2p, Im only guranteed 1 month since idk if i can make enough money gfxing for another pin but anyway, i applied it to a pure with 11 range and sucky stats.
