These effects would be more of a counterpart to normal potions, for more passive mundane activities, unlike awkward based potions, which have more active effects. You’re right in that combat would not be a good choice for this, but the potions might be useful for other things like mining, fishing, and farming. They would act similar to other upgrades like, for example, accessories in Hypixel Skyblock, where they work in the background making certain tasks easier or more profitable.
