Rings of Aggrevate Monster can be zapped now to get rings that can't be acquired otherwise. Ring of Resist Cold, Ring of Adornment, and others that remind me a lot of this game I played called "Castle of the Winds" a long time ago. They're selling for huge amounts of meat right now. I've made over 100,000 meat just selling two that I zapped. Prices will be dropping soon as supply increases.
Yay for get-rich-quick schemes that actually work for a while!
