Hey there. I have a guide on 1 defence pures on my youtube channel! Just search up RsBaus. Regarding your stats and how you should continue this build. Well, I'm guessing you finished the waterfall quest because of your 30 attack/strength, so honestly you can buildyour account into any type of pure you want (other than a obby mauler). I advise not pking at such low levels either since there's no real risk factor and like you said obby maulers dominate low level pking. I say just train up your stats and do some pure quests until you get a decent strength/range/magic level. Then go rip it up in the wildy. Your attack level should be based on whether you want to mainly use the gmaul (50), dragon items (60), or whip (70+). Just find out what kind of pure you like and go for it. Good luck.
