(00) DISCOVERY! The admixture of the two potions has caused a special formula which will cause one of the two potions only to function, but its effects will be permanent upon the imbiber.(You must determine if both effect and duration are permissible, or if only the dureation should be extended.) (91-99) Compatible result which causes one potion (randomly determined) to have 150% normal efficacy.diminution and growth, which will simply cancel each other. Potions work normally unless their effects are contradictory, e.g. (26-35) Immiscible result which causes both potions to be at half normal efficacy when consumed.(16-25) Immiscible. One potion cancelled, but the other remains normal (random selection).Both potions totally destroyed, as one cancelled the other. one potion is cancelled, the other is at half-strength and duration. (04-08) Mild poison which causes nausea and loss of 1 point each of strength and dexterity for 5-20 rounds, no saving throw possible.(02-03) Lethal poison results, and imbiber is dead if externally mixed, a poison gas cloud of 10' diameter results, and all within it must save versus poison or die.If mixed extenally, all in a 10' radius take 4-24 hit points, no save. (01) EXPLOSION! Internal damage is 6-60 h.p., those within a 5" radius take 1-10 h.p.But with the Potion Miscibility Table there is some interesting side effects that a gambling player could exploit: As the editions rolled on by, drinking multiple potions became as superfluous as drinking different colors of kool-aid, while mixing two potions together in the same container is an unthinkable action to today's gamer. This level of detail can only be found in old school D&D. Whatever certain results you settle upon for your campaign, the random results from the table apply to all other cases." it is suggested that the following table be used - with, perhaps, the decision that a 'delusion' potion will mix with anything, that 'oil of slipperiness' taken with 'oil of etherealness' will always increase the chance for the imbiber to be lost in the Ethereal Plane for 5-30 days to 50%, and 'treasure finding' mixed mixed with any other type of potion will always yield a lethal poison. You must test the miscibility of potions whenever:Ģ) a potion is consumed by a creature while another such liquid already consumed is still in effect.

"The magical mixtures and compounds which comprise potions are not always compatible. One of these oddly improbable situations is the Potion Miscibility Table (Pg 119). There's not a dull day that goes by that I can't pick up this book, flip to a random page and find something in it that I don't ever remember reading. The DMG is mostly packed with information useful to gaming yet often there are entries that are so esoterical that they border on useless. But that's the beauty of the DMG, because once in a blue moon a situation might arise in a DM's game and lo and behold Gygax has it covered. I've said this before, the 1st edition Dungeon Master's Guide is my favorite D&D book of all time.
