If I made many meal where every ingredient is the same except the potion, would the duration be different? It seems like yes but I might be delusional.
Assume same effect, tier, cauldron brewed in, but different type (throwable vs drinkable vs essence vs cauldron vs barrel).
for negative effects it’s usually gels that last the longest (except for insanity)
for positive effects it’s best to go elixir most of the time (except energy recharge, just use a gel for that one as well)
the duration of the potion is also affected by how many other status effects the meal has, so try to do as few other statuses as possible
