All genasi get saving throws against spells and effects of their respective elements. Elemental archons from F&P also gain bonuses with respect to spells of their respective elements. Dragon 310 talks about a druid alternative class that gets +1 caster level for air spells. However the only spells with the air, earth, or water descriptors are summoning spells. There are no saves for these spells, and any caster level increase for these spells is of very limited use, especially when compared to an increase in caster level for fire spells. RAW, the saving throw bonuses for earth, air, and water genasi are useless.
I think that [Air], [Earth], and [Water] should be official descriptors for spells. It would be great if WotC were to make a supplement with optional rules for this. These rules might make a good Dragon article. By adding these general descriptors, you could also have true elementalist wizards like in 2E. They would get bonus spells from their element and all other elemental spells would be prohibited.
Which spells would you classify as water, earth, or air?
