honestly, id mta bot alching w/o botting is honestly the most boring thing on rs and if u bot it, ur guranteed a ban. Plus, with mta you can make a lot of cash
I think 30m? not sure tho and if u bot smart ur guranteed not 2 get banned
I would advise you to vary the items. I assume you care about low levels of loss so use:
Green Dragonhide Bodies
Maple Longbows (u)
Yew Longs
Mage Longs
Rune Helms (not recommended).
