I'm currently playing a 11th lvl sorceress with double draconic ancestry (silver/brass). For RP purposes, I only choose her damage spells from those with either fire, cold or force descriptors. Also to reflect her double ancestry, she has a couple more spells than the usual for a sorceress.
I'd like to find a prestige class with a strong draconic flavor. Dragonheart Mage (Races of the Dragon) seems nice enough, but there is a simple complication: with a double ancestry, what would be the energy type associated with the breath weapon and the draconic feats?
I'm thinking in bargaining with the DM to let me discard the breath weapon and keep the class at full casting progression - thus removing one of the problems - but any ideas on how to deal with the free feats? Any advice is appreciated!
