On page 33 of Complete Arcane, the elemental savant's elemental specialty class feature states; "When the savant casts a spell that normally deals energy damage, its energy descriptor changes to the savant's chosen energy type, and it deals damage of that energy type instead of its normal energy type."
The way this is phrased makes me think this happens automatically, whether or not the elemental savant wants to cause their chosen energy damage or not. Does this mean that an elemental savant can't choose to deal energy damage from a type that they haven't specialized in? Seems like an awfully big limitation, especially if you're fighting monsters that have multiple immunities and resistances. Not to mention you already get this benefit from Energy Substitutuion, which is required to enter the prestige class anyway.
