OOTS #1300 - The Discussion Thread

There could be a variety of interesting effects when potions were mixed, either externally or if one drank one potion while still under the effects of another. These ranged from explosions (1%) to working normally to one of the potion effects becoming permanent (1%). I gather that that's no longer the case, that potions are now basically spells-in-bottles.

Yes, although the 5e DMG does have a table for potion mixing with odd results for some rolls. Potion Miscibility

Spoiler: The table

_d100 | Result
____01 | The mixture creates a magical explosion, dealing 6d10 force damage to the mixer and 1d10 force damage to each creature within 5 feet of the mixer.
_02–08 | The mixture becomes an ingested poison of the DM’s choice.
_09–15 | Both potions lose their effects.
_16–25 | One potion loses its effect.
_26–35 | Both potions work, but with their numerical effects and durations halved. A potion has no effect if it can’t be halved in this way.
_36–90 | Both potions work normally.
_91–99 | The numerical effects and duration of one potion are doubled. If neither potion has anything to double in this way, they work normally.
____00 |Only one potion works, but its effect is permanent. Choose the simplest effect to make permanent, or the one that seems the most fun. 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. At your discretion, an appropriate spell, such as dispel magic or remove curse, might end this lasting effect.
