# Game Systems ## Loot system After winning a fight, the player spawns in the [region](/game-info/game-systems/region.md) near the defeated opponent. The player can collect extra rewards and [blood drops](/game-info/game-systems/region/treasures.md) from the opponent’s body. The blood drops are stored in a vial, which can be used at the [Altar](/game-info/game-systems/bazaar/charatacters-and-locations/blood-altar.md) back at the base once it is full. Using the Altar allows the player to progress and unlock new content. Players can also find hidden [caches](/game-info/game-systems/region/treasures.md) in the region. These caches can be searched for valuable rewards and the ingredients needed for upgrades. ## Crafting system To add variety and strengthen items in the game, players are offered a crafting system. Players can gather ingredients to [craft potions](/game-info/game-systems/bazaar/charatacters-and-locations/herbalist.md) that improve their stats or provide temporary boosts during the game. [Crafting new weapons](/game-info/game-systems/bazaar/charatacters-and-locations/blacksmith.md) and costumes helps enhance stats and unlock new abilities for battles. Crafting paint for shurikens adds extra power and skills to their basic stats. The crafting system also solves the issue of excess items by giving them a second life. ## Trauma system After several battles and repeated hits to certain body parts, both opponents and the player’s character can suffer [injuries](/game-info/game-systems/battle/traumas.md). These injuries reduce the player’s abilities and need to be treated. At the base, a special [NPC](/game-info/game-systems/bazaar/charatacters-and-locations/herbalist.md) can help heal injuries and restore the character’s stats. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
