Making a zerker is a great choice and really rewarding. You can find a perfect zerker guide online and make sure you follow it exactly because one mess up could ruin the acc. If you follow a good guide you should be fine. Do not mix up guides stick to one guide because there is different ways to make a zerker using more then one guide can mess you up. When starting a zerker make sure you are no more than 40 att you will be getting 40-60 att all from quests. Your def xp you will get all from questing 1-45. You will end up about 42 prayer if your questing your account from 1 prayer. I believe even if you start at 31 prayer you should be fine because you will end up just before 52 prayer. I have made a few zerkers in my dayz if you have any specific questions or need any help at all you can reach out to me anytime. Also I recommend 60 att. Your combat level will stay lower giving you easier opponent, and you have soooooooooooooo much variety when it comes to pking instead of the boring old maple short to ags kills at 75 att.
