Lava



Lava is a glowing red/orange liquid found deep in the Cavern layer and in The Underworld, appearing instead of Water at depths below 1,500 feet (750 tiles) in a small world, 2,300 feet (1,150 tiles) in a medium world, and 3,350 feet (1,675 tiles) in a large world. Contact with Lava deals 80 damage per hit on players and 50 damage per hit on enemies, and inflicts the On Fire! debuff on both. Lava also slows movement the way Water does. The Obsidian Skin Potion makes players immune to Lava damage, and the Lava Charm will allow players to be safely submerged in lava for 7 seconds.

Lava flows downwards and horizontally, settling and taking the shape of any block formations below and beside it, the way Water does; however, Lava is more viscous than Water, flowing more slowly. It also emits a medium amount of flickering light. Lava can be moved by the player via a bucket or pump. After flowing 50 blocks in a direction, lava will begin to evaporate, causing the source to be lost.

Most dropped items of a Rarity lower than blue (which includes all Coins) will be destroyed when submerged in Lava past their vertical midpoint. Blocks cannot be placed directly within Lava, but falling blocks like Silt and Sand can fall into it, resulting in placement at its bottom, and these can be stacked until reaching the Lava's surface to form a safe bridge over it. Silt and Sand blocks placed this way will revert back to Lava if mined away. However, one can use this method and log out. Upon logging back in, most of the lava will be gone.

Hellstone produces half a block's volume of Lava when mined in the Underworld (a full block's volume in Expert mode). Lava Slimes create a small amount of lava when slain in Expert mode.

Crafting
Like water and honey, lava can be used as a minor crafting station. It works just like those two; in order to use it the player only has to stand nearby. Creation of items from a body of lava does not lower the lava level at all.

Used to craft
Lava can also be used to make the following items, though not as a crafting station:

Fishing
Fishing in lava requires the Hotline Fishing Hook.

Tips
A few basic techniques go a long way:

A shallow lava pit underneath a structure will kill all walking enemies as they attempt to jump towards you while you're in your house, and if shallow enough, will gather their drops in one location for easy collection later. You can also use this technique to upgrade regular pits. Standing underneath the pit will lure most enemies toward you, with even some flying enemies diving into the lava.

Lava Depth
Lava will destroy any item of Gray or White Rarity including Coins, if it is deep enough for the item to sink past its midpoint. (That is, items with larger sprites can survive deeper lava.) Generally the lava in a pit or moat should be deep enough to burn copper coins, but nothing else:
 * If too many items (over 400) accumulate in the world, the oldest ones will despawn.
 * Copper coins are the smallest and least valuable objects in the game, but each stack of them still counts as an item. An event or enemy farm can produce huge numbers of copper coins, so it's worth discarding them, against the risk of despawning more valuable items.
 * To check if a lava moat has the exact depth required, a player can throw in one copper coin, then one silver coin. The copper coin should burn, but the slightly taller silver coin should not.
 * In practice, this lava depth can be achieved with 1 Bucket of lava for each 6 to 8 tiles of pit length.
 * Thus a moat that is 6-8 blocks wide, should have one bucket thrown in, while a moat of 12-16 should have 2.
 * This implies avoiding lengths where this range can't be achieved: 1-5, 9-11, 17. A moat 18 or more tiles long can always be filled to proper depth.
 * When filling a very large moat, it is best to drop individual lava buckets over the width of the moat, and not throw it on the same spot, due to unreliable liquid physics.

Trivia

 * In the real world, lava is molten rock, but the term is usually applied only when it is expelled above ground as the result of a volcanic eruption. Lava, as found underground in Terraria, would typically be termed magma instead.
 * If you stand in lava too long, the death message says magma instead of lava.
 * The death message “Player tried to swim in lava” is most likely a reference to the exact same death message in Minecraft.
