I couldn't miss the chance to practice my drawing!
Damage floors (ダメージゆか, Damēji Yuka?) are a recurring feature in the series, most prominent in early installments. They are often traps in nature, damaging the party's HP either by a minute amount each step, or by reducing them to critical HP. In most installments that they appear in, the player is forced to walk through damage floors in order to progress in dungeons, though in some games, the player may press switches or use certain abilities to bypass damage floors.
When in Mount Gulg and the Hellfire Chasm, the player will have their HP damaged when walking on lava. In addition, walking on sharp stalagmites in the Cavern of Ice or in the Whisperwind Cove will also damage the player. In addition, a specific floor in Whisperwind Cove will have the player constantly lose HP while walking around on it. Random encounters don't happen on damage floors.
In the Mysidian Tower, the player can be damaged if they walk through lava or ice spikes, which is sometimes required in order to proceed in the dungeon. In the Cyclone, walking across electrified floors will damage the player, and in Jade Passage and Raqia, the player can be slightly damaged by walking underneath the waterfalls. In the Leviathan, walking in the stomach acids will damage the player slightly.
In the Nintendo DS version, the only instance of damage floors appear in the Molten Cave, where standing in the lava will constantly damage the party. In the Famicom version, this does not happen as the lava is just water colored red.
In the Sylph Cave and the Passage of the Eidolons, the player may be damaged if they step on green tiles (for the Sylph Cave) or red tiles (for the Passage of the Eidolons). These tiles also appear in the Advance remake in the Lunar Ruins. However, if the player casts Float on the party in the menu before walking across these tiles, they can avoid taking damage. An interesting note is that if Teleport is cast while on a damage tile in the SNES version, and the characters are not floating, up to 2,100 damage will be inflicted on the party.
On the North Mountain, if the player steps on the purple flowers, they will be poisoned. When inside Castle Exdeath, the Great Sea Trench, and the Sealed Temple, the player may be damaged if they are standing in lava. In the Istory Falls, the player will be damaged when they step on the spikes located in certain places in the dungeon. However, if the player has a Geomancer in the party or knows and has equipped the Light Step passive ability, they can avoid taking damage.
In the Phoenix Cave and the Dragons' Den, the player will be damaged when they step on the spikes located in certain areas inside the dungeon. They deal 400 points of damage every time they land or walk on them. They disregard status ailments, so a Petrified character will still be hurt by them. Also, the spikes will never KO a character; if a character has 400 HP or less, it'll set the amount of current HP to 1. This can be avoided if the player steps on the switches controlling the spikes.
Cave to the Sealed Gate, falling into the lava when on the moving platforms damages the party for 8 HP.
Only a few areas in the game have floors or specific areas that damage the player. In the Cave of the Gi, if the player runs across an area covered in brown liquid in the third screen instead of walking, the player will be thrown into a wall of spikes. In the Ancient Forest, if the player steps on a flytrap, the party's HP will be reduced to 1. Ironically enough, if a party member is at 0 HP, they will be revived with 1 HP when this happens.
Final Fantasy XII does not feature damage floors, and the only hazards which on-foot travel represents are stationary traps. The Firemane fought in the Garamsythe Waterway continually loses HP when it is standing in water, as if afflicted with Sap, but this does not affect player characters.
Traps damage the players that step on them. There are various kinds of traps, some of which even heal the party, but most of the time, traps deal damage and/or negative status effects to anyone in range of a party member who triggers one. The player can cast Float to avoid traps, or wear Steel Poleyns. Traps become visible with the Libra status.
The Disc of Cauthess in Duscae and the Rock of Ravatogh volcano in Cleigne feature sections wherein the floor is burning and will damage the player if they walk on it. Daurell Caverns have sections with poison on the floor that similarly damages those who walk upon it. Zegnautus Keep floods some of its hallways with poison gas, inflicting poison when walking through them.
The player will find the first damage floor in Kett, Glaive's Airship, Glaive Castle, Davias' Mansion, Cave of Ruins, Dime Tower, and Temple of Mana. These spikes will be sticking out of the floor. Stepping on them deals a good portion of damage to Sumo. There is also lava found within the Undersea Volcano. A third one, an energy field deals the most damage out of all damage floors. This one appears within Glaive's Airship, Glaive Castle, Cave of Ruins, and Dime Tower.
The player will come across lava right at the entrance to the Undersea Volcano on the overworld map, as well on the inside. The party will take 1 points of damage for every step they take on the lava. Inside the volcano, it is filled with lava as well.
There are two forms of damaging floors in the game, the first the player encounters is in the form of lava in both the Crevasse and Mt. Goht. The second is in the form of electricity in Xagor's Castle. If the player walks into these two specific floors, the party will take 2 points of damage for every step they take on these floors.
There are several damage and status ailment floors: Blind Gas which inflicts Blind in Harena Ruins, Poison Swamp that inflicts Poison in Miasma Woods, the Hushleaf Spore that inflicts Silence in Florem Gardens, and magma in Underflow that 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. The Dungeon Master support ability learned by Freelancers at job level 4 allows the entire party to avoid the effects of such floors and traps.
The Pandaemonium (Ω) stage in Dissidia Final Fantasy has floors that change in color from gray to red and black. Red and black floors will shoot out spikes that can damage opponents on or just above the floor, adding the Brave stolen to the stage's Brave pool.
