Yo, #dungeonsanddragons Twitter – help me solve a disagreement.
You can choose to not resist a spell that has a saving throw, but can you choose to not resist a potion that has a saving throw?

As written you can't voluntarily fail a save unless the effect specifically says you can (e.g. Calm Emotions).

I so dearly wish I could fail that save like several times a day. Right? Totally built in to use as a positive benefit for your allies (suppressing charmed and frightened, and madness effects).
