[@Pathfinder] Hmm, having not thought about it before I've decided on the spot that "potions" exist, but they aren't magical in nature, think of them like caffeine shots and energy drinks that some warriors might use to give themselves an edge in battle, at the cost of possibly becoming addicted and gaining a resistance to their effects if used too often.

Among the very, very few that exist, all magical objects, abilities and artefacts belong to select Lore characters and might be discovered or even obtained through IC interaction.
