Lava immunity time is recharged gradually by exiting lava, the same way breathing time is recharged by exiting water (albeit much more slowly). When the Lava Charm is equipped and the player comes into contact with lava, a 7-second countdown begins, signified by a lava meter that displays over the player's head, which operates similarly to the breath meter, but displays flame icons instead of bubbles. Map viewers are useful for finding Floating Islands and other resources, as well as providing a total world view not otherwise attainable. On the Old-gen console version, Windows Phone version, Old Chinese version, Nintendo 3DS version, and tModLoader 1.3-Legacy version it can only be found in Chests, but can be found throughout all of the Caverns. Map viewers are 3rd-party programs that analyze saved maps and display their contents in one easily-viewable graphic. On the PC version, Console version, Mobile version, and tModLoader version, it can be obtained from Hellstone Crates and Obsidian Crates with a 5*1/20 (5%) chance, or in Chests in the lower portion of the Caverns where lava pools can naturally spawn.
The Lava Charm is an accessory that grants immunity to lava for 7 seconds.
