Energy Damage in a Vacuum

In a vacuum like space, there's no medium for energy transfer through conduction or convection. Cold, fire, and electricity spells or actions with the cold, fire, and electricity traits don't function in a vacuum. Ignore these rules if the spell or action targets an adjacent target, even if it uses a ranged attack roll. This rule can be especially oppressive and should be avoided if the PCs are reliant on these abilities, and you should feel free to exempt specific traits. Magical effects or weapons with magical upgrades bypass this effect—magic breaks normal physics!
