The Daricassan worship the deity Moradin, God of the Forge.
Daricassan have the following modifications to the PHB Dwarf entry:
-2 Dexterity, +2 Constitution:
Gold Dwarves are tough enough to survive the brutal environment of the desert, but they rely more on cunning and fast talk than agility.
+1 racial bonus on attack rolls against humanoids of the reptilian subtype (including kobolds and lizardfolk) and dragons (including half-dragons): Gold Dwarves are trained in special combat techniques that allow them to fight common enemies more effectively. This bonus replaces the normal Dwarf’s bonus against orcs and goblinoids.
+4 dodge bonus to Armor Class against dragons: This replaces the dwarf’s dodge bonus to AC against giants. Dragons are a more common threat than giants in desert climes, and Gold dwarves have adapted to meet this challenge.
+2 racial bonus on Knowledge (architecture and engineering), Knowledge (dungeoneering), and Profession (miner) checks: Gold Dwarves protect a great deal of information about what lives beneath the desert and how to reach it.
No racial bonus on Craft checks.
