Well It took me about a week to get 63 mining and got about 450k out of it!
Took about a day for att and about 2 days for str! I am currently working on 55 str!
65 mining probably wouldn't take you more than a few hour so you could pull that off first. 1-40 ranged probably would take you about the same time as 65 mining depending on where you train so its best you do mining first and then ranged.
Nice acc man. 70 range is possibly the main level you can put up some serious damage. 40 is a must. 40 attack is fine at that, str can vary from 60-80. mining, you can basically do w/e you want with that.
