This Proposal only has further effect if there is a “Potions” Rule.
Change the paragraphs in the “Potions” Rule that begin with “There is also one other…” and “An Unidentified Potion’s…” to

There is also one potion not on the Basic Potion table: the Unidentified Potion.  When an Unidentified Potion is added to an @‘s inventory, let N be the result of a DICEX roll, where X is the number of items in the Basic Potion table.  If the Nth Potion in the Basic Potion table is on that @‘s Discovery List, that @ gains that Nth Potion and loses the Unidentified Potion.

An Unidentified Potion’s Primary Effect is “Let N be the result of a DICEX roll, where X is the number of items in the Basic Potion Table that are not on your Discovery List.  Carry out the Primary Effect of the Nth item in the Basic Potion Table that is not on your Discovery List, and add that selected Nth item to your Discovery List.”

Whenever some positive number M items on the Basic Potion Table are added to an @‘s Discovery List, for each Unidentified Potion in that @‘s inventory, let N be the result of a DICEX roll, where X is the number of items on the Basic Potion Table that were not on that @‘s Discovery List immediately before the addition of the M items.  If N is less than or equal to M, that Unidentified Potion changes into the Nth item of the M items that were added to the @‘s Discovery List.

If, somehow, an @ has an Unidentified Potion in its inventory for some positive amount of time, but all items on the Basic Potion Table are in its Discovery List, delete that Unidentified Potion from the @‘s inventory and then give that @ a Potion of Water.  This paragraph does not prevent an Unidentified Potion that is added to the @‘s inventory from existing long enough to be replaced by a random potion as described earlier in this Rule.

In the Basic Potion Table, move the Potion of Water to the first position of the table.
