An inferno of unrelenting heat.Final Fantasy Tactics: The War of the Lions description
Lava (熔岩, Yougan?) is a recurring terrain type in the Final Fantasy series. Lava's role is to damage the party when they walk upon it in the majority of its appearances, and in others acting like an impassable barrier.
Inside the Mysidian Tower, the player will be damaged when they walk through the lava.
In the 3D version, simply standing in the lava inside the Molten Cave will constantly damage the party. In the Famicom version, this does not happen as the lava is merely coded as water and given a red palette.
Lava acts like a barrier on the underworld: the player cannot cross it by walking and can only fly over it with the help of an airship. Inside the Passage of the Eidolons, lava will damage the player once stepped on. It also appear in the Advance remake in the Lunar Ruins. However, if the player casts Float on the party before walking across the lava, they will avoid taking damage.
Lava damages the player when steeped in. Casting Float mitigates the damage.
Lava causes damage if it is stepped in. If the player casts Float they will not be damaged.
Castle Exdeath, the Great Sea Trench, and the Sealed Temple have areas within it that contains lava that damages players standing within it. If the player has a Geomancer in the party, or has equipped the Light Step passive ability, they can avoid taking damage.
The Phoenix Cave and the Dragons' Den are the only areas that have lava, and it acts as a barrier by preventing the player's progress. In the Cave to the Sealed Gate, falling into the lava when on the moving platforms damages the party for 8 HP.
Lava also appears in parts of the Labyrinth of the Ancients.
There's a terrain tile called Lava and it only appears in Mount Bervenia. A Geomancer standing on the Lava terrain tile will use Magma Surge to deal Fire-elemental damage with a chance of inflicting KO to any enemy units within five squares.
Lava will be first see before the entrance into the Undersea Volcano on the overworld map, as well within it. The party will take 1 point of damage for every step they take on the lava. Inside the volcano, it is also filled with lava as well.
Lava acts like a barrier and prevents the player from crossing inside the Underflow. Magma found within the area will damage the party's HP, but it cools down and will allow the player a chance to run across it before heating up again. When it heats up, it glows fiery red.
