Terrain

Terrain is a mechanic in which gameplay on Zones of the playing field is affected by the area of land they cover, usually by granting a Field Power Bonus. In the manga and anime this concept was used during the Duelist Kingdom tournament. In is also used in some video games. This concept is not used in the OCG/TCG, although a number of Field Spell Cards are based on it.

In Yu-Gi-Oh! Forbidden Memories, Field Spell Cards create terrains that increase or decrease a monster's ATK and DEF by 500. Depending on the location, a terrain may already be in place.

Yu-Gi-Oh! The Duelists of the Roses is played on a grid and each tile has its own terrain.

Cards which affect terrains

Field Spell Cards can change the terrain in video games that use this mechanic. In the manga and anime, Field Spells had not been introduced at this point.

In the anime and manga, the following cards were shown to affect the terrain:

• The fireball attack from "Winged Dragon, Guardian of the Fortress #1" is able to light up the Night field for a second, making the opponent's DARK monsters visible.

• "Swords of Revealing Light" can completely light-up the Night terrain, revealing the opponent's monsters.

• "Burning Land" can be used in conjunction with "Curse of Dragon" to burn away certain terrains.

• "Full Moon"/"Mystical Moon" can raise tide levels, causing the Ocean terrain to spread to more Zones. Destroying "Full Moon"/"Mystical Moon" causes them to drastically drop.

• "Shadow Ghoul" could be fused with the Labyrinth terrain to create "Wall Shadow". "Wall Shadow" could move through the walls and more spaces than its Level. The Labyrinth remains intact when "Wall Shadow" is destroyed.

• "Magical Labyrinth" can be used to rearrange the walls of the Labyrinth.

• "Dungeon Worm" can tunnel under the "Labyrinth".

In Yu-Gi-Oh! The Duelists of the Roses the following cards affect terrains:

• "Labyrinth Tank" can move on Labyrinth squares.
