To further advance in a dungeon, a player must find the stairs. On the last floor of most dungeons, it will take the team out of the dungeon. The stairs can go up or down, depending on if the player is to descend to the dungeon's basement floor or ascend to the top of it.
Varying numbers of these can be found on a floor, if the dungeon contains them at all. If there is a yellow arrow above the player's or partner's head (indicating a stat problem such as lowered defense, accuracy, etc.), stepping on one of these will restore the normal state. However, it also cancels stat increments of the Pokémon.
In certain dungeons, there is a chance that the team may encounter a Training Switch in a room. Stepping on a Training Switch gives the leader and their teammates the Trained status, which allows their moves to receive more points so their moves can be upgraded more easily.
Sometimes, the player may find sparkling floor tiles in a room. Stepping on a sparkling floor will either make an enemy Pokémon appear, make the player pick up a Gold Bar or a rare item.
Traps are special dungeon tiles that cause negative effects. These tiles can make the team's Pokémon lose HP, PP, inflict status conditions, etc. These tiles will not affect enemy Pokémon unless spawned by a player's Trapper Orb. Issue #47 of Pokémon News claims that at least Pitfall Traps are appearing because of recent natural disasters.
In Gates to Infinity, most of the same traps return from prior games; however, many traps in Gates to Infinity have been redesigned or renamed, and unlike the previous games, all of the traps break after being triggered. The first dungeon to have low-tier traps in them is Telluric Path, the high-tier traps start appearing in the dungeons that are unlocked after completing the main storyline.
In Super Mystery Dungeon, all the traps that appeared in Gates to Infinity return. All the traps' boarders have a slight change than they were in it's predecessor. And traps also appear more earlier in the game than it's predecessor and the low tier traps first appear in Glittering Mountain.
The Pokémon that steps on this trap will cause the user and it's allies to be affected by a Discord! This trap breaks after being triggered. This trap is the only trap in the game in which never appears in the Adventure Hints, even when it is first encountered.
Similar to the Selfdestruct Trap, this trap explodes when stepped on and does damage to Pokémon within a 2-tile radius. It will take away half of the player's and allies' current HP, and does 80 damage to wild Pokémon. It also destroys items and walls within the radius. If a Pokémon with the Ability Drizzle or Damp is present on the floor, or if the current weather is Rain, the trap will have no effect. Fire-type Pokémon will only take half damage.
A random few Apples, Big Apples, Huge Apples, Gummis, or other edible food sources in the player's bag will be turned into Grimy Food. Grimy Food restores the player's Belly by 30, but inflicts a status condition. This trap has no effect on items in the bag when activated by allies.
Pokémon with a Survivalist IQ can sometimes bypass this side effect.
Sends the Pokémon that triggered the trap flying 10 squares in a random direction. If the Pokémon hits another Pokémon or a wall it will lose 5 HP (as will the other Pokémon in the former case), and if it lands on a tile that it cannot walk on, it will warp.
In Gates to Infinity and Super Mystery Dungeon, this trap breaks after being triggered.
Reduces the Pokémon's belly by 10. If the Pokémon has less than 10 belly left, their belly will go down to 0. If the Pokémon that has 0 belly left is the leader, the leader will take 3 HP damage each turn. This trap breaks after being triggered, however in dungeons with high-tier traps in them, it can be triggered three times before breaking.
If the player steps on it, it will inflict 5 HP damage and drop the team one floor below; and if it's the last floor of the dungeon, the dungeon will be cleared. When an ally steps on it, the team member will be instantly removed from the dungeon. If a client as part of a mission steps on it, the mission fails and the team will return to base. Pitfall Traps will only appear in dungeons that have stairs going down.
There are many other tiles present, which limits the access to only specific Pokémon.
Water tiles - Special areas of water, which only Water-type Pokémon, Pokémon who fly or levitate, and Pokémon with the IQ skills All-Terrain Hiker, Super Mobile, or Absolute Mover can walk through. Dive can only be used on these tiles and Dig cannot be used on these tiles.
Lava - Special areas of lava, which only Fire-type Pokémon, Pokémon who fly or levitate, and Pokémon with the IQ skills All-Terrain Hiker, Super Mobile, or Absolute Mover can walk through. However, a Pokémon that is not a Fire-type will be burned when walking through lava. Dig cannot be used on these tiles.
Walls - Walls surround dungeons; however, some Pokémon which seem to fly or levitate, such as Ghost-type Pokémon, can pass through on top of them. However, passing through walls makes the Belly drop five points per turn (this does not affect partners or enemies because they do not have Belly points until switched into a leader). Walls can also be passed through if the player uses a Mobile Orb, holds a Mobile Scarf, or has the IQ skills Super Mobile or Absolute Mover. In Gates to Infinity, the leader loses HP instead.
Air - Holes in the dungeon's floor that can only be crossed by Flying/Levitating Pokémon or those with the IQ skills All-Terrain Hiker, Super Mobile, or Absolute Mover. Dig cannot be used on these tiles.
