I see none of you have botted 99 strength before.
There is NO WAY he will get 99 strength in one week even if POTTED/PRAYING/MAX STR GEAR 24hours a day.
He need 12mil exp, for him to get that in 7 days he would need to get 72k str exp/hr 24 hours a day, nonstop.
REALISTICALLY you're looking at 3-4 weeks of "suiciding". (which you won't be able to run 24/7 anyhow)
im 70 att, 75 str, 75 def.
