The bunny chest mats are prohibitively expensive on my world, almost 1m for the sage used in exp buff potion and almost 500k for the water, so nobody uses the exp potion and none have sold on marketboard for the 1.4m price a few sellers are trying.

I think S-E intended bunnies to be played a lot by making it auto spawn constantly and conveniently positioned near the home point. It just confused people by taking the appearance of a Fate but offering zero exp. There aren't many people who understand its purpose or value the potential rewards.
