When I had 61 Magic, I spent around 500k on runes, and got Infinity bottom (was 2.85M back then) ...My magic afterwords was 69, and I gained almost 2.3M.
Took me 10 days..Now infinity bottom is impossible to sell (Seriously - Notice how the price is dropping)
Unless you trade it to another person for some items (What I did)
Good luck =/ It took me 10 days, but it was very frustrating.
enchant part is very good xp and if you can enchant d stones (like meh ) then a good quick way is to pick up all d stones (6 of them) enchant em all with the d stone enchant thingy and u get 10 points (60 points all together) and then just hop world i did this for about 15minutes got 2.4k points XD
