Crafting and Upgrading Leather Flasks

Starting with the Leather Flask

Craft a Leather Flask first. It is the base container for carrying Purified Water. Fill it by using it on a Copper Cauldron or Campfire Cauldron that holds Purified Water. A full flask lets you drink while exploring without returning to your base.

Upgrading Through Smithing

Take your Leather Flask to a smithing table. The smithing_transform recipe upgrades it step by step:

• Iron Leather Flask
• Golden Leather Flask
• Diamond Leather Flask
• Netherite Leather Flask

Each tier increases how much Purified Water the flask holds. Gather the matching metal or gem plus your current flask, then apply the smithing transform. Work upward in order — you cannot skip straight from Leather to Netherite without the intermediate tiers.

Keeping Flasks Full

Refill any flask tier at a heated cauldron containing Purified Water. If you run low, place a Rainwater Collector to gather water, then boil it in a Copper Cauldron or Campfire Cauldron. Use a Bamboo Pump to move collected water into the cauldron automatically.

Carry a spare Purified Water Bucket as backup for long trips. When a flask empties, pour from the bucket into the cauldron, reboil if needed, and refill. Upgrading to a Diamond or Netherite Leather Flask reduces how often you must stop to refill.
