"Adventurer's Porter"
Flax Seed and Sacred Lotus seeds : Feather
it has a "damage health" as well, but with flax seed first, it should read as "feather" instead of "damage health". and at mastery / expert levels, it only damages HP 1pt for 1sec (If you have higher end alchemy equipment) and gives you a LOT of feather (170 - 300, skill and intel level dependent) which can last upwards of 300 seconds.
plus it weighs zero, another bonus.
but you can always go "flax seed" + "Lady's Mantle Leaves" for a non-damage health version... and I must say this potion saves my life, especially as Sacred lotus are everywhere in the imperial city (over 110 of them all together, havestable every three days ^^ ).
and flax seeds are found all over the wilderness - lady's leaves are in shops for the most part, I've yet to find a good concentration of them in the field but hey
Sweetrolls can be substituted in, as they also have 'feather'.
