A creature's base movement speed determines the maximum amount they can Move in a single action under normal conditions. It is determined by the creature's MOV attribute and is equal to 30 + (10 × MOV) in feet per action. A creature's base movement speed alone does not actually determine how far it can move in practice. Every creature has speeds for different types of movement, such as walking, leaping, swimming, climbing, and flying. The possible speed adjustments are double, normal, half, quarter, and none. Moving 5 feet at half speed uses 10 feet of movement, while moving 5 feet at double speed uses only 2.5 feet of movement. The following table summarizes the different movement speed adjustments.
| Speed Adjustment | Cost of Moving 5 Feet |
|---|---|
| Double | 2.5 feet |
| Normal | 5 feet |
| Half | 10 feet |
| Quarter | 20 feet |
| None | Cannot move in this way at all |
The default speed adjustments for different types of movement are as follows.
| Movement Type | Speed Adjustment |
|---|---|
| Walking Speed | Normal |
| Difficult Terrain Walking Speed | Half |
| Crawl Speed | Quarter |
| Swimming Speed | Quarter |
| Climbing Speed | Quarter |
| Hidden Speed | Quarter |
| Leaping Speed (horizontal) | Quarter |
| Leaping Speed (vertical) | None |
| Flying Speed | None |
| Digging Speed | None |
