Violent Volcano

Violent Volcano is the fourth world that the player will encounter during a run (Unless the player does World 4 Darkness). There are a few new droid appearances inside of this world, such as Pyro Droids and Ghost Droid 3.0s.

Environment
Violent Volcano, as its name suggests, is a volcano (although a very weirdly shaped volcano). It has a dark brown floor and walls. Environmental objects that can be found here include rocks, rock pillars and geysers.

Violent Volcano's environmental hazard is lava. Unlike water and quicksand, which deal a fixed amount of damage and teleports the player out of it when touched, lava applies a burning effect on the player when touched, dealing high damage spread out over time. The player will not be teleported out of the lava; staying on the lava will constantly refresh the burn duration and deal more damage. After leaving the lava, the player will continue burning for a few seconds. This allows the player some time to react by consuming a healing item, unlike water and quicksand which deal damage instantaneously.

Lava appears quite frequently in the world, and can appear in various shapes. Lava can be frozen by Freeze/Melt buttons that may appear in certain rooms, although these buttons are not guaranteed to appear. The Cinnamon Sword also freezes lava on lunge. Alternatively, the Elementalist's second ability can be used to freeze lava.

Geysers can be found in multiple rooms in the world. Geysers periodically spew out steam, causing players that stand on the geyser to be pushed far upwards. Jumping when a geyser activates increases the boost. Geysers do not damage players.

Trivia

 * The Cinnamon Sword is capable of freezing lava despite it dealing fire damage, making it a valuable item to purchase from World 3 Shop or before.
 * The paladin's first ability negates the burn damage from lava, but does not stop the burn effect from being applied; if the forcefield runs out while the player is on fire, they will start taking damage even if they are not currently stepping on lava.
 * Strangely, all droids are immune to lava.
 * Violent Volcano and Crystalline Caves are the only worlds to have an alliteration in their names. (since the addition of Stone Sanctuary and Gingerbread Glaciers, this is no longer true.)
 * Coincidentally, both worlds feature lava.
 * The song that plays in this world is called Mudeth - Outside the Fold.
 * (Block) is able to negate all lava damage, even though lava does not deal all its damage instantly like quicksand and water.
