I have 78 magic, and I want to get to 80, and I was thinking of using the humidify spell, how much xp per hour is it? Are there any better spells?

I've heard 35k exp/hr, give or take. I don't know what the profit is in the current market, but pretty sure it's fairly decent. You could feel good about training with humidify--it's a great option.

 

 

 

I've also had some success enchanting air orbs...managed to do something like 500 in an hour with a terrorbird, which is close to 40k experience and however much profit. Like 185k gp/hr or something, I dunno.

Thanks a lot for the help, that really helped me decide =P
