Lava is a power and a special type of tile. It is closely related to fire and heat.  

== Lava Types ==
There are four types of lava in worldbox:

* [[File:tileLava310x0.png|frameless|40x40px]] Level 4 lava 
* [[File:tileLava210x0.png|frameless|40x40px]] Level 3 lava
* [[File:tileLava110x0.png|frameless|40x40px]] Level 2 lava
* [[File:tileLava010x0.png|frameless|40x40px]] Level 1 lava

Lava can change between levels by using the Temperature power:

* Using the [[Powers|Temperature (Hot)]] power increases the lava level by 1
* Using the [[Powers|Temperature (Cold)]] power decreases the lava level by 1, or turns level 1 lava into hills
Lava continuously damages all units in it (except [[Demon|demons]] and [[Fire Elementals|fire elementals]]), each time dealing 150 damage. Units with the fireproof trait are not immune to this damage. 

Lava was also probably designed to set units on fire; however, due to some issues in code, it will only set on fire [[Piranha|piranhas]] and demons who have the burning feet and fireproof traits removed.  

== Lava Generation ==
Lava can be generated from different sources:

* Using the [[Powers|Lava]] power to manually place them
* Spewed from active [[Volcano and Geysers|volcanoes]]
* Dropped from [[Clouds|lava clouds]]
* Generated when terrain is heated to a certain extent by [[:Category:Destructive|heat rays]]

== Lava Spread ==
When the [[World Laws|Eternal Lava]] world law is disabled, lava can spread and cool naturally. The time it takes for different levels of lava to spread is different:

* [[File:tileLava310x0.png|frameless|40x40px]] Level 4 lava takes at least 0.6 months to spread 
* [[File:tileLava210x0.png|frameless|40x40px]] Level 3 lava takes at least 2 months to spread 
* [[File:tileLava110x0.png|frameless|40x40px]] Level 2 lava takes at least 2 months to spread 
* [[File:tileLava010x0.png|frameless|40x40px]] Level 1 lava can only cool, and cannot spread. It takes at least 6 months to cool after which it becomes hills. However, it will not cool if there are level 2 or higher levels of lava in adjacent positions. 

When lava spreads from a tile, the lava level in the original tile decreases by 1. The target tile of the spread will change according to the following rules:

* If the target tile is a '''level 1-3 lava tile,''' then the spread occurs, and the target tile's lava level increases by 1.
* If the target tile is a '''level 4 lava tile''', then the spread will not occur.
* If the target tile is a '''non-lava tile which can "contain lava"''' - these tiles include hills, mountains, and infernal biome tiles - the spread will not occur. 
* If the target tile is a '''non-lava tile which cannot contain lava,''' then the target tile will be converted to level 1 lava.
When lava of levels 2-4 attempt to spread to a tile, it will unfreeze the tile or set it on fire.
