I had a script on another bot refilling stealth rings from depot. I got from level 13(exori tera) to level 35 very quickly with that script.
You could do it manually just buy stealth rings and go kill cyclops (mistrock or cyclopolis in edron)
8-15 Larvas
15-33 Cyclops/Any Tomb-2
33-50 Earth Elementals
50-100 Water Elementals
Fastest way to level 100 while botting and you won't waste too much, just carry stealth rings on Cyclops and energy rings on earth elementals (3+)
