Yeah I've never really dungeoneered in that world, just heard many stories about it
I suppose ivy isn't too bad xp wise, it could be slow like divination and agility
Sadly there's no possible way to
afk
agility without spending more than it's worth.
As for divination... it seems boring and I wouldn't really consider training it at current prices and xp per hour.
I afk at roarius with silverhawk boots whenever I get feathers to come with them since it's fast xp... I went from 71 to 75 agility before running out of charges on them if I remember correctly.
