Nature's Amulet.

So i've been thinking about diseased plants and how to prevent them, since sometimes we venture far from our bases not knowing when the disease will strike, and come back to find a bunch of bushes diseased and that's very inconvenient. Now i'm not saying remove the disease, i like this challenge element.
But i'm suggesting to have an endgame item that warns you about it even when you're far from base.

The Nature's Amulet. Similar design to the rest of the amulets but using a green gem to craft it. If worn (loses durability while worn) it will warn you if your plants are going to be diseased like 1-2 days ahead of time, so that if you're far from base you can make it back in time to prevent it from spreading.
