Surprised it took so long to get a bot for this. That being said, it does a great job. As an iron I always mentally knock points for bots that aren't iron friendly but it's still a 5/5 for everyone else so I rate it as such.
I recommend the option of super energy potions instead of only staminas.
I'll update with total run time for Ash Covered Tome, Full Mining Outfit, and Broken Dragon Pickaxe.
I'd guess around 20 hours total.
