I have noticed that herblore has gotten fairly inexpensive recently. I have 85 right now and I could get overloads right now. I realize that turmoil is more of a priority, but it is expensive right now. Let me know what I should do. Thanks bunches.

I would personally either: go for herblore now, seeing as it's relatively cheap, or hold off on the decision until after the proposed prayer/demon ash update. I'd expect the cost of prayer to fall a bit with the introduction of more ways to get experience.

Herblore would be your best bet atm seeing the prices of d bones and frost bones beeing extremely high.

No point waiting for the prayer update to come out as u will eventually have to get both ovs & turm.
