All these noobs that say 2 def does not matter are the noobs I kill in the wilderness. Yes it matters. It is already ruined, your best bet is to go zerker if you want to salvage that 90 range and magic. Make SURE you read the most up to date zerker guide you can find before doing anything. have EVERYTHING planned out to avoid ruining. This is how most accounts get ruined. Spending 1 hour preparing is worth it when you bot for 2 months and realize "oh shit, that quest will level this stat I don't want leveled".
Also, @ ll champ
Wtf? 52 prayer? The MOST a pure will ever need is 31. I like to stay at 13.
The 52 prayer you suggest will be good for a zerker however.
