Pokémon field moves
All the attacks below can be used outside of battle,
in the field. Some are used for story progression,
while others are simply useful to have.
Cut is used to tear down small trees in your path. It can only be used with the appropriate Gym Badge (usually from the second Gym of the game).
Defog can be used to clear foggy areas (fog will return upon leaving and re-entering the area). So far only Sinnoh has experienced foggy weather. In Diamond & Pearl, Defog cannot be used outside of battle before obtaining the Fen Badge (Pastoria City Gym); In Platinum it cannot be used before the Relic Badge (Hearthome City Gym).
Dig can be used to escape from caves. The player is returned to the entrance they took, just like using an Escape Rope.
While surfing, if you happen over a dark patch of water, you can dive below the surface and explore underwater. Two regions have areas where you can dive: Hoenn (Ruby, Sapphire, Emerald) and Unova (Black, White) and Dive is an HM in those games.
Lights up dark caves. In the original games dark caves made the screen almost completely black, whereas in later games you can always see a very short distance around you; Flash merely expands that circle.
Fly allows you to fly instantly to any Pokécenter you have already visited during the course of the game (or certain other prominent locations). It is usually obtained late in the game, long after you obtain the appropriate gym badge.
In Gold, Silver, Crystal, and the remakes HeartGold & SoulSilver, Headbutt can be used to shake trees. Often wild Pokemon will fall out; some Pokemon are only obtainable via this method.
In the field, using Milk Drink will take away 20% of the user's maximum HP and give it to another Pokemon. (It is unusable if the user's HP is below 20%.)
Can be used to ascend rocky paths, in Generation 4 only.
Breaks certain rocks that may be in your path. Smashing rocks may uncover wild Pokemon or items. Breakable rocks appear only in Generations 2-4. Rocks in Sinnoh do not reveal Pokemon nor items when smashed.
In Generation 3, Secret Power allows the user to create their own secret base when used on weeping willow-like trees.
In the field, using Softboiled will take away 20% of the user's maximum HP and give it to another Pokemon. (It is unusable if the user's HP is below 20%.)
Used to move large boulders in the field. Boulders can only be pushed, not pulled.
Surf can be used to cross water. While surfing, wild Pokémon may appear. From Generation 3 onward it's possible to fish while surfing; previously one could only fish at the water's edge.
While standing in grass, Sweet Scent will make a Pokémon automatically appear.
If the user is outside, Teleport will instantly transport you back to the last Pokemon Center you visited. It does not work in caves or buildings.
Allows a surfing Pokémon to ascend a waterfall. Except for Diamond, Pearl & Platinum, you do not need a Pokémon knowing the move in your party to descend waterfalls.
Whirlpool allows you to cross swirling maelstroms in your path. (Only Generation 2 and Generation 4 have Whirlpools that can be passed.)
