The only reliable way to heal in Witchfire is to consume a spherical capsule called a health elixir. It regenerates health points over time and removes any elemental effects or ailments. However, everyone starts with only one health potion, which is not enough once you start exploring higher-difficulty maps or upgrading your Gnosis levels. This is especially true for players new to rogue-lite games since Witchfire carries a certain degree of challenge.
