When you click "Bottom's Up!", the Sorceress will inform you of your Potion result, whether your Trophy Goblets have triggered and which the Effects for your city productions!
If you have more Trophy Goblets, you have to keep drinking more of the potion to have a chance of triggering more effects; in the top right corner, you have the information on how many Trophy Goblets you have left!
Sometimes, the same effect can be repeated; in which case you will have to choose whether you want to keep the old one or select the new one, which can be better or not; the choice is always yours! Only one effect of the same type can be active simultaneously in your City!
If a Trophy Goblet does not trigger a Potion Effect in which you have used Spell Fragments, part of the used Spell Fragments will be refunded to you! You will see this information in the Potion result window, and at the same time, the announced amount of Spell Fragments will be refunded.
