What Luck!
From Twilight Heroes Wiki
As you're patrolling the streets of the neighborhood, you pause to examine a clump of clovers growing up through a crack in the sidewalk. Somehow, even in the dim light of a buzzing streetlamp, your heroic eyes manage to glimpse a four-leaf clover sticking out of the clump. As you bend down to pick it up you realize there's a 20-chip piece nestled in between the plants. Someone must have dropped it in the dark. Bad luck for them, but good for you!
You gain 20 chips.
