It will be around 2.3mil. But, my maximum spend is 3 mil. Maybe a dragon skirt. But I'm not sure what I should buy for RS gold the plate.
The torso truly is the most effective "free " body in the game. The sweet str reward is intoxicating and you should get it today. Kill cyclopses in warrior guild, and progress to a rune defender, Get tokens by completing the strength & defence mini-games within the warriors guild ( the easiest 2 and your def and str are under 70 ).
D-Legs as well as D boots/rune boots/climbing shoes and Neitiznot Helm ( a better str boost than the zerker). The thing about the Neitiznot is that you must do a quite annoying task to wear it, however like the torso it is worth the effort. The quest is called fremmenik Isles. You can combine DDs + Whip with the glory charm and you are good to buy OSRS gold go.
