I was around level 30 and really lazy to level. Since Rift is more of an end-game MMORPG, I created a simple (like 300 lines) Instant Adventure Script. All it does is AFK there, but it teleports from place to place and has the option of looting every thirty minutes, leaving the party every hour, and loading coordinates that are automatically saved upon running the script(You have to manually set all the coordinates). I've been using it for around a week and didn't have any problems at all, except that I kept dying in 25+ IA groups. It got me a good amount of sourcestones (around 200+ sub 40 and 11k after 40) and leveled me from 30-50 in no time.
Now, the real question is, would any of you guys use it if I released? For all you AutoIT coders, if you decompile my script it's kind of messy since PixelSearch doesn't work on Rift (trust me, I've tried everything!).
