# How is total movement speed calculated for creatures with different movement types?

### Rules Questions

Hello friends!

I can't find any direct reference to this in the books, so I figured I would ask on here and hope someone else has had this question.

If a creature has multiple movement types; e.g. a Crocodile with land speed 20 swim speed 30, then how is the total distance he can move in a single move action across varied terrain calculated? Let's say the crocodile is presently in water deep enough for him to move his swim speed, and he is 10 feet from the shore. He has to use up 10 of his 30 swim speed to get to shore, but then does he have to stop and take another move action to move on land? If he can keep going on land, then how much further can he go? Does he just get the 20 land speed in addition to the 10 he's already moved by swimming, or is it reduced by some fraction? The same question in reverse: if the crocodile were on land, 10 feet from the shore, then how far into the water could he swim after moving 10 of his 20 land speed to get to the water?

If this question is already answered somewhere else, then please direct me to it and excuse my ignorance.

I'm not sure if there are rules for that. I would go by fractions. in the second example the crocodile used half his move on land so he can still take half his move in water, which would be 15ft.

In the first example it gets trickier because it's not everything about full 5ft increments.
the croc swims 1/3 his move so it has 2/3 left. 2/3 of 20ft is about 13,3ft which equals 10ft (movements shorter than 5 ft are neglected). So it could still move 10ft on land.

An example (and thus a precdent) of movement shorter than 5ft being ignored if the elven barbarian favored class bonus. They get 1ft bonus to base move per level they chose the bonus but it has no effect untill they got it 5 times.

Just to add to what Umbranus said, you can think about it as "how far can this character move in X amount of time?"

On land, in "one move action": 40 feet
In water, in "one move action": 60 feet

So, as Umbranus said, just think of things in terms of "half a move", "a third of a move", etc. The fact that the game doesn't use those terms doesn't mean you can't; just make sure everything adds up to "one move action" (or two, as the case may be).

And, also as Umbranus mentioned, remember to round down.

As far as I know there's no official ruling on this.

I've seen it done several ways.

1) Round the movement to the nearest easily divisable amount. For example, I have swim 20, move 30, and I swim 10 feet and wade out of the water. I've used half my swim in the move, so I have half my normal land movement left, and move an additional 15 ft. Reversed, with swim 30 and move 20, you round down, so you swam 10 ft, have 2/3rds of your movement left. Since 2/3rds of 20 doesn't easily work to a 5ft amount, you go with half, or 10 feet of movement.

2) You can only use one method of movement per movement action. So swim 10 feet to shore, end movement. Use a different movement action to move 20 feet on land.

3) Use the shortest distance for all movement. In the case of your example, the shortest movement is 20 feet (land) and so you move 10 feet swimming and then 10 feet on land.

All 3 work, with 2 and 3 being simpler than 1, but less 'realistic'. Just pick the one you like best.
