The Elixir Bar

The artificer Tsarina deconstructed the legendary distillery of Kren, and remade it into a more stable potion bar operable by magewrights.

Any reasonably intelligent creature that has the ability to cast spells may expend a spell slot and one hour to generate upto 4 potions. The potion created is determined by a d20 roll modified by either Intelligence or Wisdom modifiers. The user may specify any potion upto the result of the roll. For example, on a roll of 15, the user may create any combination of four potions listed at the values of 1 through 15.
