Note: this guide is written to reflect the placer of the bubble with a 5 person+ group. If you are a participant, you can expect to profit around coins as there will be no input costs.
Raw rocktails are in demand both because of the good Cooking experience they give and because of the high-tier healing power their cooked variant gives. Rocktail bubbles last for long enough to give 20 – 28 rocktails per person. With other participants, you will almost definitely reach your cap of around 60 rocktails .
Once daily, a player may create one divine location of any kind. In addition to this, the player has a limit on how much they may harvest from any divine location. This limit is almost always reached from a single divine rocktail bubble with 5 other people. The time for creating and harvesting from divine locations resets every day at 00:00 UTC.
