control weather + control winds

[aquaticrna]

Just a couple (hopefully) quick questions, first being, control weather and control winds can be stacked on top of each other correct? thus producing a calm area in the enormous storm, or an area of, absurdly high wind speeds. the second is, for the wind effects produced by these two spells do you use the normal fort save as per the spell or the fort save that that weather normally requires? logically it would seem that there would be no reason for your 51 mph magic winds to be any harder to resist than normal 51 mph winds but since when do the rules of dnd stick to logic :smalltongue:

edit: oh one other thing! control weather lasts "twice as long" for druids as other characters, so when using a sudden extend on that would that mean 4x as long, or 3x as long? combing that with a maximize is the difference between 6 days of constant weather control and 8 days of control ;)

Stacking rules for real quantities (like mass, or speed in this case) use normal math for the multipliers. So it'd be 4x.

Does Control Winds stack with another Control Winds?

Does Control Winds stack with another Control Winds?Only if they're instantaneous.

Otherwise it's the same effect and they overlap.

It seems like they would stack as long as you did control winds 2nd except that control weather is already capable of creating the maximum wind speed some of the time, or else only 1 step below it. I don't think you can go beyond tornado. Reducing the wind speed to protect the party is a neat trick though. In either case the violent weather would impose a concentration check. Let's see by then your concentration would be 16 + con modifier and the DC is 17 + wis modifier. Your wis is higher than your con but it still looks like an easy roll.
