You have greater connection with your distant draconic bloodline.
Prerequisite: Sorcerer level 1st.
Benefit: You gain the dragonblood subtype. Choose one dragon from the Draconic Feat Options table and gain the indicated skill as a class skill. This is your draconic heritage, which cannot be changed once the feat has been taken. Half-dragons must choose the same dragon kind as their dragon parent.
In addition, you gain a bonus on saving throws against sleep and paralysis, as well as spells and abilities with the energy type of your Draconic Heritage. This bonus is equal to the number of draconic feats you have.
The Draconic Feat Options table provides the benefits of the Draconic Heritage feat for all the kinds of true dragons published in D&D version 3.5 volumes to date.
Many of the draconic bloodlines listed on the table don’t grant a bonus on saves against effects of a particular energy type. Instead, you gain a bonus on saves against spells and abilities associated with the effect (such as force for the Tarterian dragon) or subschool (such as compulsion for the chaos dragon) that matches the entry on the table, as well as the normal bonus provided by the feat against magic sleep and paralysis effects.
Special: A character who chooses yu lung as his draconic heritage can, when he selects another draconic feat, choose to change his draconic heritage to any other lung dragon (chiang lung, li lung, lung wang, pan lung, shen lung, t’ien lung, or tun mi lung). Once this choice is made, it can only be changed by undergoing the Rite of Draconic Affinity.
Consult with your DM as to which dragons are actually present in a particular game before selecting one for this feat.
Sources: Races of the Dragon, page 102. This feat also appears in Complete Arcane, page 77, and Dragon Magic, page 17. While the latter source is the latest, its text is essentially the same as that in Races of the Dragon, which has a far more inclusive table of dragon types to use with this feat, the Dragonic Legacy feat, and the Dragonwrought feat. For that reason, the Races of the Dragon version deprecates the others.
