Bloodbag

Bloodbag is a crafting and cooking ingredient obtained from killing Leeches in the Swamp. It is a common mid-game material and becomes important once you start preparing higher-tier food and mead bases. Leeches drop Bloodbag in quantities that scale with their star level, with higher-star enemies yielding more.

Bloodbag is used in several key recipes, especially swamp and frost progression items. It is required for:

• Black Soup
• Blood Pudding
• Mead Base: Frost Resistance
• Mead Base: Medium Healing
• Swamp Dweller's Delight
• Red banner

These recipes make Bloodbag valuable well beyond its origin biome. Black soup uses only a single Bloodbag and is one of the earliest notable food uses, while Blood pudding and Swamp dweller's delight consume larger amounts and are associated with more advanced cooking. It is also a core ingredient in both frost resistance and medium healing mead bases, making it relevant for exploration and survival in harsher biomes.

Because Bloodbag comes from Leeches, it is most efficiently gathered in Swamp water where they spawn. Since Leeches are aquatic and hostile, collecting Bloodbag usually goes hand in hand with swamp travel and combat. Players who spend time in the Swamp will naturally accumulate it, and the item becomes a stockpile resource rather than something to farm only for a single recipe.

Bloodbag is also used in crafting the Red banner, so it has a small decorative application in addition to its food and alchemy uses. Its recipe list shows that the item remains useful across multiple stages of progression, from simple cooking to more specialized preparation at the cauldron and mead ketill.
