The Lesser Healing Potion is the baseline recovery elixir crafted by mixing 2 Bottle units, 2 Gel, and 1 Mushroom, producing 2 potions at a time. It also appears abundantly by smashing surface pots, looting wooden chests, or buying supplies directly from the Merchant.
Early boss survivability and potion upgrading
Consuming a dose replenishes 50 health and triggers 60 seconds of Potion Sickness. While invaluable during early cave exploration and initial boss encounters, combining 2 of these elixirs with 1 Glowing Mushroom upgrades them into a standard Healing Potion that doubles medical efficiency.
Trivia
Consuming a Lesser Healing Potion restores 50 health on use and triggers standard Potion Sickness.
