DMG p140 has a potion miscibility table. Artificer subclass Alchemist creates Experimental Elixirs. Can these elixirs be combined for a roll on the aforementioned table?

Variant: Mixing Potions is already an optional rule, so it is entirely up to the DM.

It is already up to the DM to decide if they want the Potion Miscibility table to apply to mixing potions. The artificer's elixirs seem to behave very similarly to potions, so a DM could reasonably rule that Potion Miscibility applies to the elixirs as well if they have already decided to use these optional rules for traditional potions.


Yes, if the optional rule is used.

The rules for mixing potions is a variant rule that a DM has the option to use if they want. The optional rules state:

A character might drink one potion while still under the effects of another, or pour several potions into a single container. The strange ingredients used in creating potions can result in unpredictable interactions. When a character mixes two potions together, you can roll on the Potion Miscibility table. If more than two are combined, roll again for each subsequent potion, combining the results.

This is a general rule for combining potions and does not specify any limitation with regard to where the potions come from or how they were made. In fact, the item doesn't even have to be a "potion." The last effect reads:

For example, a potion of healing might increase the drinker's hit point maximum by 4, or oil of etherealness might permanently trap the user in the Ethereal Plane.

A page earlier (139), the rules state:

Different kinds of magical liquids are grouped in the category of potions: brews made from enchanted herbs, water from magical fountains or sacred springs, and oils that are applied to a creature or an object. Most potions consist of one ounce of liquid.

In other words, "Potion" is a catchall term for a "consumable magic item" as the book calls them. Further underlining this is the fact that the variant rules use oil of etherealness as an example of something that could have a new effect when mixed.

This makes it clear that the variant rules are intended to work with a wider array of magical brews than just things strictly called "potions." To wit: oils, elixirs, etc.

Absent some sort of rule stating that the experimental elixirs created by the Artificer somehow do not qualify as belonging to this broad "potion" category, they do since they are perfectly described by it.

Thus, it is up to the DM to decide if the rule is to be used, so check with them.

    \$\begingroup\$ @Vitto The DM has final say in all matters. S/he can veto whatever they want and it would be legitimate :) \$\endgroup\$

    \$\begingroup\$ @The As I point out in my answer, the example provided by the miscible "potion" rules themselves use an oil as an example of something that can be mixed. I think it's a mistake to look at the word "potion" in the title and ignore the fact that the full text doesn't limit the rules to only items called "potions." \$\endgroup\$

    \$\begingroup\$ @vit Why does it matter if the elixirs are made using spell slots, are impermanent? None of these disqualify them from being classified as potions according to the description. \$\endgroup\$

    \$\begingroup\$ @vit If your player wants to gamble with his/her gut like that, they are going to expend all their elixirs pursuing long odds. And if they do hit that discovery and "some harmful effects could result" as well. Seems like a good way to balance things to me. Frankly, as a DM, I'd welcome this kind of mad scientist play. It's true to the archetype. \$\endgroup\$
