I was using some grinder profiles and i just felt that while they did their job, leveling still went slow, especially since the newest update. So I tried a pet battle profile to level some battle pets(at the time I did not know you got player exp as well). Well I found that you get a ton of exp while doing these with the right profile. From 90-100 I was averaging 400-500k exp per hour(no joke). I usually run the bot for 180 min sessions  and then have it automatically cut off for a few hours, then rinse and repeat. No detections or reports that I’m aware of so it seems pretty safe.

Anyone else have success in power leveling a toon this way?

best way is with the hat, and on pet battle bonus weeks .. its an easy few lvl 110s

What hat?
