I am an Ice Wizard crafting the Watchtower Hall from Grizzleheim. I tried to buy the Nature's Wrath Recipe from Blossom in Ravenwood, it wouldn't let me. Okay, where can I possibly battle for these cards. I know people are going to suggest using a life wizard and then trading cards. I don't know how to do this either. Thanks for all your help - anybody!
I think that the Fickle Pickle occasionally drops these. But you need 32 cards for the GH house, so you really have to find a life wiz to make them for you. Or start a wizard of your own for this purpose--the Nature's Wrath cards only require apprentice crafter status, so your wizard only has to get through Krok crafting. I am working on the house myself, or I would be happy to help. I find that the grassy mounds--which also require a ton of water lilies--are the hardest part of the whole thing. :(
I eventually did use my Life Wizard to make the cards, and my husband helped me with the trading. And, your right, the Water lilies are the worst. KI has made a lot of the reagents easier to find. Maybe they can work on the water lilies too. There should still be a way to get the Nature's Wrath Treasure Cards from Bosses and Gardening. There should be other options!
