Potion Miscibility

[Yaskin_Forrit]

Way back in version 1 of the DM Guide, there was a potion miscibility table (below)

When taking multiple potions, the DM could roll to see what happened.

I have been in groups where one person downs multiple pots - e.g. barkskin, prot & res pots, foxes/bears/bulls etc.

imagine the chaos that would result if this table was used

Dice - Result
01 - EXPLOSION! Internal damage is 6-60 h.p., those within a 5” radius take 1-10 h.p. if mixed externally, all in a 10’ radius take 4-24 hit points, no save.
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.
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; one potion is cancelled, the other is at half strength and duration. (Use random determination for which is cancelled and which is at half efficacy.)
09 – 15 - Immiscible. Both potions totally destroyed, as one cancelled the other.
16 – 25 - Immiscible. One potion cancelled, but the other remains normal (random selection).
26 – 35 - Immiscible result which causes both potions to be at half normal efficacy when consumed
36 – 90 - Miscible. Potions work normally unless their effects are contradictory, e.g. diminution and growth, which will simply cancel each other.
91 – 99 - Compatible result which causes one potion (randomly determined) to have 150% normal efficacy. (You must determine if both effect and duration are permissible, or if only the duration should be extended.)
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. (Note that some harmful side effects could well result from this. . . )

Yes for a Pen and Paper game, where Potions are limited...

No to DDO where potions are literally weighing most low level characters down as if they were a pack mule.

Don't nerf my backpack page full of pots.

That was ad&d we are based on 3.5 they dumped that little chestnut long ago and good ridance.

Yep, was an old option.

Was rather intended for a low magic setting where magic is rare and lore not common and dangerous.
On a high magic world the lore is fairly advanced and potion makers don't have these problems, have better reagents, etc.

The newer rule that makes this possible is the potion brew feat being limited to low level spells, hence less risk.
To brew higher level potions you instead make one-use items with the craft wondrous item feat.

That would take FOREVER to code every single possibility and outcome for every single mixture of potions.

Comparing 1E D&D to 3.5/DDO is like comparing golf to baseball - yes, you're hitting a white ball but they're not even remotely close to the same game.

I thought I had posted this in the general section -- deffo not a suggestion

Maybe your subconcious betrayed you :P
But anyways, this miscibility is pretty much the precursor of potions of wonder
