Green Dragons' Breath vs Gust of Wind

[Exquisite Dead Guy]

Would it be possible for an arcane caster to ready an action to cast gust of wind to counter a green dragon's breath weapon?

Sorta... I believe anyone in the line is safe. Cones work like spreads though so 'i think' the caster has to make himself subject to the gust of wind to avoid the gas.

Would it work on a red dragon's breath as well? After all, fire is a gas.

Slept through physics class, I see.

Fire isn't a state of matter (like a gas, or a liquid) at all. It's an exothermic chemical reaction, when combustible material is rapidly oxidized.

Fire is not a gas last time i checked the game rule and the laws of reality say otherwise as well.

The spell calls out what it does to fire. Against a larger fire source i would say the fanning of the flames adds 1d6 to the fire damage per spell level of the gust of wind.

In my campaign, I distinguish between "fire" and "heat." The spells are called protection from heat, resist heat, etc. Thus, the red dragon is creating a cone of heat in front of him. Wind gust does not affect energy effects.

Incendiary cloud produces burning gas, but by and large fire is not gas.

Of course, the game already does grave violence to fundamental physical concepts (in most games, there are only the four classical Greek elements of the elemental planes, rather than ~130 - I'm continually astounded that people generally ignore such a huge fundamental change), so if you want fire to be a gas in your campaign, go for it.
