Inkwhistle Draught
Brewed by a long-dead librarian-archivist whose spirit never quite abandoned her collection, Inkwhistle Draughts smell faintly of aged parchment and candle smoke. Flecks of what appear to be tiny printed letters float suspended in the pale grey liquid, dissolving the moment the vial is uncorked. Scholars say the ghost still haunts the original library's ruins, cheerfully correcting anyone who mispronounces an author's name.
Mechanics
Drinking this potion lets ghostly whispers from a forgotten library guide your hand, granting advantage on the next Intelligence (History) or Intelligence (Arcana) check you make within the hour.
Whispers of the Stacks
When you drink this potion (no action required beyond the action to drink it), flickering spectral text swirls through your vision for up to 1 hour. During this time, the next time you make an Intelligence (History) or Intelligence (Arcana) check, you roll with advantage. After that one check resolves — or when the hour expires — the effect ends. As a minor cosmetic flourish, small ghostly letters drift visibly from your fingertips until the effect ends, though this produces no mechanical benefit or penalty.
DM Notes
This is a purely utility potion with no combat impact, appropriate for level 1–3 play. The advantage on a single knowledge check is equivalent to the guidance cantrip in a narrow context, making it a fair common-rarity consumable. Consider placing it in libraries, archives, ruins, or in the possession of NPC scholars. Because it offers no combat benefit, it is safe to hand out freely as flavor loot. The cosmetic floating-letters effect can be a useful roleplay prompt — NPCs who notice it might react with curiosity or mild alarm, creating light social interaction opportunities.
