Is there a rule regarding how much damage is inflicted if something runs into an object?
For example, if there is a blind individual that performs a move action into a wall, what happens?
Let's add some permutations to this example.
What if the individual used a charge action? What about a run action?
What if they ran into another person?
What if they ran into a pane of glass?
What about individuals with different movement speeds? Does a monk with 70 ft. move speed run into a wall faster than a dwarf with 20 ft. move speed using the same action?
Is there a rule regarding how much damage is inflicted if something runs into an object?
Other than the falling rules, no.
For example, if there is a blind individual that performs a move action into a wall, what happens?
He stops.
What if the individual used a charge action? What about a run action?
They stop.
What if they ran into another person?
Overrun or bullrush.
What if they ran into a pane of glass?
Glass has a hardness of 1 and 1 hit-point per inch of thickness. See the damaging objects rules.
Or this one with math in it down near the bottom.What about individuals with different movement speeds? Does a monk with 70 ft. move speed run into a wall faster than a dwarf with 20 ft. move speed using the same action?
Yes, but the additional speed has no effect beyond that built into skills like Jump.
