Pretty simple trinket idea: a lucky clover that increases the chance of getting rare loot from bugs and resource nodes. It would be relatively rare drop from clovers.

Some drops, like beetle horns and widow fangs/venom are so rare that collecting them for crafting or upgrades can require clearing the entire yard multiple times. And certain trinkets are so rare that I've still not encountered them with several hundred hours in the game. Just having a trinket that can be equipped when farming for a particular resource would be a good trade-off to help reduce the grind, without making things too common.

I second this idea!
