Dense Fog states that it is represented by clusters of cloud effects, although most Event Organizer do not seem to use the 3” template clusters, but instead use mousepad terrain of various sizes.
The cloud effects are still cloud effects, no matter what they “represent”. It’s the definition of “dense fog” that is unexact, not the definition of a cloud effect.
So yes, Wind Burst should delete Dense fog cloud effects that are in the spellcaster’s control range (not necessarily the whole Dense fog cluster, only those cloud effects in the cluster that are in the spellcaster’s CTRL).
If everybody used the actual cloud effect templates to represent Dense Fog, I would agree with you and not ask here, but as most people use something different and do not represent it with “clusters of cloud effects”, I am still wondering if Dense Fog would be affected.
No one gets to circumvent the rules of the game just because the physical representation of a piece of terrain doesn’t match the general description.
I can “represent” a forest with a jar of applesauce. If the players have agreed that the piece of terrain is a forest, then the piece of terrain is still a forest, as far as the game is concerned.
Dense Fog is Dense Fog, no matter what physical representation players use. Period, full stop.
…and the definition of “Dense Fog” is “cluster of cloud effects.”
If two players agree that a piece of terrain is Dense Fog, then it is Dense Fog, which makes it a cloud effect — regardless of whether or not there’s a 3” AOE template on the table, or a mousepad, or a takeout menu, or what.
But either way Dense Fog would be affected by Wind Burst, whatever may be used to represent it in the table, right?
What I mean is, Dense Fog does (per rules and / or infernal ruling) indeed count as a cloud effect, thus there is no scenario in which Dense Fog should not be affected by Wind Burst, correct?
