Move in Other Environments

Water 

Move is normally Basic Move/5, rounded down. You can increase water Move directly for 5 points per yard/second, or reduce it for -5 points per yard/second. Members of land-dwelling races must have Swimming skill to increase water Move, and cannot buy more than +2 yards/second. If you’re Amphibious, both water and ground Move equal Basic Move, and changes to Basic Move adjust both scores. If you’re Aquatic, water move equals Basic Move and ground Move is 0.

Air 

Move is 0 without special advantages. 

If you have Flight, air Move equals Basic Speed x 2 (not Basic Move x 2). You can increase air Move directly for 2 points per yard/second, or reduce it for -2 points per yard/second. If you have Walk on Air, your air Move equals your ground Move, because the air is like solid ground beneath your feet.
