Honestly i'd just level up your main and pk on that, other wise make a pker account that has a good Chance/record of surviving full rune Dm's, i've been pking on my main for quite a while with good results for an account that "shouldn't" be a good pker according to standards. (90 atk 99 str 86 def 70 pray 94 hp) The majority of no armor fights i get into risk little to nothing, so it follows that i don't get much of a reward, apart from the occasional corrupt. Recently i've started full rune dms in pvp worlds, these are much better imo, the game gives me a much better reward for downing full rune as opposed to a rune scim, which is really all you would kill as a pure pker. typically drops equal full rune and up with as little as 25 ep. But if you're really set on making the 5millionth pure, go with bballer
