When a character tumbles (at half speed) during a
move action, does that mean he is moving at half speed for
the whole move, or just in the squares where tumbling?
Although it’s easiest to apply the half-speed penalty to the
entire move action, it’s not strictly necessary to do so.
If the player and DM can handle this additional level of
complexity, it’s perfectly okay to rule that you pay an extra
movement cost only for each square that you use Tumble to
exit without provoking an attack of opportunity (as well as for
each square of an enemy’s space that you enter using Tumble).
For example, imagine Ember begins her turn 10 feet from
an orc and wants to use Tumble to move through its space and
end up 15 feet away on the opposite side.
• Her first square of movement wouldn’t provoke attacks of
opportunity (since she’s not leaving a threatened square), so
she doesn’t use Tumble or move at half speed.
• Her second and third squares of movement take her
through the orc’s space, so these effectively cost twice normal
(that is, they each cost 1 extra square of movement), and this
movement requires a DC 25 Tumble check. (If you’re using
this system, it’s much easier to think of tumbling as costing
extra squares of movement rather than actually changing your
speed.) Ember has now paid a total of 5 squares of movement
(out of the 8 allotted to her for her speed of 40 feet).
• Assuming that check succeeds, Ember now moves from a
threatened square (adjacent to the orc), which requires a DC 15
Tumble check and costs twice normal (or 1 extra square of
movement). She’s now paid a total of 7 squares of movement.
• Finally, Ember moves one last square, ending up 15 feet
from the orc on the opposite side from where she began. She’s
not leaving a threatened square, so she doesn’t use Tumble or
pay any extra movement. Ember has paid for 8 squares (40
feet) of movement, and has covered a linear distance of 5
squares (25 feet).
从这里可以看出不是仅仅对一个人做一次这么简单
