Before we make the sheet we just wanted to know if any changes should be made to the main idea. It's a small trinket or medal, usually a pendant. The charm binds to the wearer and they can no longer use healing spells or healing potions of any kind. However, it will increase recovery abilities from resting and even slowly heal more serious wounds like broken bones. It also counts as about a few extra Heart Containers to increase the general durability of the wearer. Clooby has been contesting the idea and wonders what changes or fixes would make this a better Treasure entry.
The main idea seems good to me. The Library intentionally doesn't reference Heart Containers, though, since that can be arbitrary. Even across the canon series, an nearly attack that takes 2 hearts in LoZ will only take a 1/4-heart in the Wind Waker... If you'd like, I'd be fine with designing a "sheet" and seeing if you and Cloud would approve it. (Of course, you can just design the sheet yourself if you'd prefer, and hopefully that would make a fine entry too.)
