If you want to train it with controled then be my guest. i trained my str att and def to 91 b4 i set out on 99 attack. now i have it and 500k from 98 str. but my def is still the same. the reason i waited till all my skills were 91 b4 i set out to get 99 att was cuz i wouldn't have that much longer till another 99 to trim my cape. and slayer is a great way to make money/charms/xp till a 99. Gl in what u choose :P
