You gain the dragonblood subtype. Choose one kind of dragon from the list in the accompanying table. This is your draconic heritage, which can only be changed by undergoing the Rite of Draconic Affinity (see page 59). Half-dragons must choose the same dragon kind as their dragon parent. When you declare your draconic heritage, you gain the skill indicated on the table as a sorcerer class skill. In addition, you gain a bonus equal to the number of draconic feats you have on saving throws against magic sleep and paralysis effects, as well as on saves against spells and abilities with a descriptor that matches the corresponding entry in the accompanying table. (See RDr p103). Draconic Heritage for All True Dragons. The table above provides the benefits of the Draconic Heritage feat for all the kinds of true dragons published in D&D products 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.
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 (see page 59).
