How much movement do you expend when using Spider Climb to go up a wall?


Rules Questions


You are in a 5-foot wide 10-feet tall hallway with your ally in the square in front of you. You want to use Spider Climb (already active), to move into the square above your ally.

How much movement do you use to get there with your 15-feet Climb speed?

Scenario 1:
1) Move 5-feet up the side of the wall in your square.
2) Move 5-feet vertically.
3) Move 5-feet into the ceiling.
4) Move 5-feet over your ally.

Total Movement: 20-feet, a double move.

Scenario 2:
1) Move 5-feet up the side of the wall in your square.
2) Move 5-feet diagonally on the wall above your ally.
3) Move 5-feet into the ceiling.

Total Movement: 15-feet, a move action.

Scenario 3:
1) Take a 5-foot diagonally to the square above your ally.

Total Movement: 5-feet, not an action.

Please advise.

If I'm picturing this correctly, I'd need to know how high the ceiling is.

This is based on the following assumptions: 10' high wall (2 squares to ceiling).

You (with active Spider Climb) in the middle(ish) of the 5' square next to the wall with your ally in the square in front of you.

1) It would be 5' of movement to advance diagonally (5' for first diagonal movement) to the wall directly next to your ally (pick a side, left or right)
2) One square of movement up (brings you to one square above your ally, but still on the wall

if you want to stop here, you are now out of your ally's square (total of 2 squares of movement), but if you want to continue to the ceiling directly above your ally, then one square of additional movement would be required (total of 15' of movement).

Either way, it's a movement action, not a 5' "step".


Sorry, I just edited the original post. Yes 10-foot high.

Also, I could see (depending on your DM and how close you were to the wall to start) that it could be ruled that you were already on the square on the side of the wall, in which case it would be 5' of diagonal movement to bring you directly above your ally on the wall, then another 5' to bring you to the ceiling directly above your ally.

Still, this would be 10' of movement and require a move action.


If you and your ally are both medium creatures, and the hall is 10 feet tall floor to ceiling, you couldn't occupy the square directly above him without constantly head-butting each other.

That said, I'd put it at 15 feet of movement to get up there.


So you have to treat each surface as if it was horizontal movement?


Yes. The confusion I can see is how you occupy the square you start in. Presumably you have to move from the horizontal plane to the vertical one 5'. But the game abstracts where you are in your square. You can move in any direction and only count the new square for movement. Would this abstraction allow you to be on the wall (your first 5') when you started moving?

Personally, I would rule that it would require that first 5' of movement to move from the floor to the wall, but I could see making an exception to my own rule depending on how my players had described their character's actions in setting up the scene. Most of the time, yes, treat each surface as horizontal movement.
