Flex Potion
Gain 5 Strength. At the end of your turn, lose 5 Strength.
Flex Potion is strongest in turns where burst attack damage matters more than long-term setup.
Best for players who treat potions as tactical resources and want to convert one key turn into survival, burst damage, or a cleaner scaling line.
Saving Flex Potion for a “perfect” moment instead of using it in the fight where it actually changes the outcome, the pathing risk, or the resource tradeoff.
Potions are not long-term deck pieces, but they often decide the most dangerous fights in a run. That makes them uniquely important in Early Access, where many decks are still incomplete and cannot rely on perfect internal consistency.
A strong potion page should not just repeat the effect text. It should help you understand what kind of fight, turn, or build context turns the potion from “nice to have” into “run-saving”.
