Whipping Rocks is a "cone" spell .. it is cast outward in the shape of a cone and has an effective range. If you stay outside that range (I believe it is the same range as "thrown") ... you can cast "rod" spells and use missile attacks.
But, using this strategy will cause the GeoMancers to do the same .. so instead of casting Whippping Rocks, they will use something else from their bag of tricks.

Going to have to agree with the getting closer bit.Run in and once you're in melee range on the casters, have your healers start doing some healing while your fighters take their shots. Focus on the casters before the elemental and have your party setup so that the elemental is going to go after those that can take the brunt of the attack.
Also, utilize any bombs you may have. I don't think the casters will be around long if they have 6 area affect bombs going at them.
