I am getting the same things when I buy bags of herbs. It would be nice to be able to trade in multiple herbs for more rare herbs. It would help to go faster through the game. For example, the Puzzle pieces spell. I am spending way too long on one area up to 2 to 3 days for puzzle pieces...Just so I can move forward..

I don't know if a trade-in would be my fave way, but I'd love to see one more sack of herbs avaailable to buy. Right now, you can buy 1, 2 or 4 herbs. It would be nice if there were a bag of 8 herbs - OR, just as effective, allow us to buy 1 of EACH bag every 20 hours, not just 1 bag (period) every 20 hours.

I second Mindy's request...you could somehow make the trade process more difficult than the gem trades, to with the "not leveling up too fast" thing. Or trade mana for a certain herb. There are spells I haven't been able to use at all, because I haven't gotten that herb yet!

I think it's important not to depend on herbs when you begin the game, and rather, to not even buy the bags initially either. Just keep collecting the easy-to-get ones until you max out some of them, then start buying the bags. When you start maxing out on the higher-level ones is when you should actually consider beginning to use them.

They're all obtained via the same methods, just at differing likelihoods.
