Movement, Position, and Distance

Source PRPG Core Rulebook pg. 192
Miniatures are on the 30mm scale—a miniature of a 6-foot-tall man is approximately 30mm tall. A square on the battle grid is 1 inch across, representing a 5-foot-by-5-foot area.

Tactical Movement

Source PRPG Core Rulebook pg. 192
Your speed is determined by your race and your armor (see Table 8–3). Your speed while unarmored is your base land speed.

Encumbrance: A character encumbered by carrying treasure. a large amount of gear, or fallen comrades may move slower than normal (see Chapter 7).

Hampered Movement: Difficult terrain, obstacles, or poor visibility can hamper movement.

Movement in Combat: Generally, you can move your speed in a round and still do something (take a move action and a standard action).

If you do nothing but move (that is, if you use both of your actions in a round to move your speed), you can move double your speed.

If you spend the entire round running, you can move quadruple your speed (or three times your speed in heavy armor). If you do something that requires a full round, you can only take a 5-foot step.

Bonuses to Speed: A barbarian has a +10-foot bonus to her speed (unless she’s wearing heavy armor). Experienced monks also have higher speed (unless they’re wearing armor of any sort). In addition, many spells and magic items can affect a character’s speed. Always apply any modifiers to a character’s speed before adjusting the character’s speed based on armor or encumbrance, and remember that multiple bonuses of the same type to a character’s speed don’t stack.

Measuring Distance

Source PRPG Core Rulebook pg. 192
As a general rule, distance is measured assuming that 1 square equals 5 feet.

Diagonals: When measuring distance, the first diagonal counts as 1 square, the second counts as 2 squares, the third counts as 1, the fourth as 2, and so on. You can’t move diagonally past a corner (even by taking a 5-foot step). You can move diagonally past a creature, even an opponent.

You can also move diagonally past other impassable obstacles, such as pits.

Closest Creature: When it’s important to determine the closest square or creature to a location, if two squares or creatures are equally close, randomly determine which one counts as closest by rolling a die.

Moving Through a Square

Source PRPG Core Rulebook pg. 193
You can move through an unoccupied square without difficulty in most circumstances. Difficult terrain and a number of spell effects might hamper your movement through open spaces.

Friend: You can move through a square occupied by a friendly character, unless you are charging. When you move through a square occupied by a friendly character, that character doesn’t provide you with cover (see page 195).

Opponent: You can’t move through a square occupied by an opponent unless the opponent is helpless. You can move through a square occupied by a helpless opponent without penalty. Some creatures, particularly very large ones, may present an obstacle even when helpless. In such cases, each square you move through counts as 2 squares.

Ending Your Movement: You can’t end your movement in the same square as another creature unless it is helpless.

Overrun: During your movement, you can attempt to move through a square occupied by an opponent (see page 201).

Tumbling: A trained character can attempt to use Acrobatics to move through a square occupied by an opponent (see the Acrobatics skill).

Very Small Creature: A Fine, Diminutive, or Tiny creature can move into or through an occupied square. The creature provokes attacks of opportunity when doing so.

Square Occupied by Creature Three Sizes Larger or Smaller: Any creature can move through a square occupied by a creature three size categories larger than itself.

A big creature can move through a square occupied by a creature three size categories smaller than it is. Creatures moving through squares occupied by other creatures provoke attacks of opportunity from those creatures. Designated Exceptions: Some creatures break the above rules. A creature that completely fills the squares it occupies cannot be moved past, even with the Acrobatics skill or similar special abilities.

Terrain and Obstacles

Source PRPG Core Rulebook pg. 193
From tangled plants to broken stone, there are a number of terrain features that can affect your movement.

Difficult Terrain: Difficult terrain, such as heavy undergrowth, broken ground, or steep stairs, hampers movement. Each square of difficult terrain counts as 2 squares of movement. Each diagonal move into a difficult terrain square counts as 3 squares. You can’t run or charge across difficult terrain.

If you occupy squares with different kinds of terrain, you can move only as fast as the most difficult terrain you occupy will allow.

Flying and incorporeal creatures are not hampered by difficult terrain.

Obstacles: Like difficult terrain, obstacles can hamper movement. If an obstacle hampers movement but doesn’t completely block it, each obstructed square or obstacle between squares counts as 2 squares of movement. You must pay this cost to cross the obstacle, in addition to the cost to move into the square on the other side. If you don’t have sufficient movement to cross the obstacle and move into the square on the other side, you can’t cross it. Some obstacles may also require a skill check to cross.

On the other hand, some obstacles block movement entirely. A character can’t move through a blocking obstacle.

Flying and incorporeal creatures are able to avoid most obstacles.

Squeezing: In some cases, you may have to squeeze into or through an area that isn’t as wide as the space you take up. You can squeeze through or into a space that is at least half as wide as your normal space. Each move into or through a narrow space counts as if it were 2 squares, and while squeezed in a narrow space, you take a –4 penalty on attack rolls and a –4 penalty to AC.

When a Large creature (which normally takes up 4 squares) squeezes into a space that’s 1 square wide, the creature’s miniature figure occupies 2 squares, centered on the line between the 2 squares. For a bigger creature, center the creature likewise in the area it squeezes into.

A creature can squeeze past a creature while moving but it can’t end its movement in an occupied square.

To squeeze through or into a space less than half your space’s width, you must use the Escape Artist skill. You can’t attack while using Escape Artist to squeeze through or into a narrow space, you take a –4 penalty to AC, and you lose any Dexterity bonus to AC.

Special Movement Rules

Source PRPG Core Rulebook pg. 194
These rules cover special movement situations.

Accidentally Ending Movement in an Illegal Space: Sometimes a character ends its movement while moving through a space where it’s not allowed to stop. When that happens, put your miniature in the last legal position you occupied, or the closest legal position, if there’s a legal position that’s closer.

Double Movement Cost: When your movement is hampered in some way, your movement usually costs double. For example, each square of movement through difficult terrain counts as 2 squares, and each diagonal move through such terrain counts as 3 squares ( just as two diagonal moves normally do).

If movement cost is doubled twice, then each square counts as 4 squares (or as 6 squares if moving diagonally). If movement cost is doubled three times, then each square counts as 8 squares (12 if diagonal) and so on. This is an exception to the general rule that two doublings are equivalent to a tripling.

Minimum Movement: Despite whatever penalties to movement you might have, you can take a full-round action to move 5 feet (1 square) in any direction, even diagonally. This rule doesn’t allow you to move through impassable terrain or to move when all movement is prohibited. Such movement provokes attacks of opportunity as normal (despite the distance covered, this move isn’t a 5-foot step).
