As the manifestation of Dahak was destroyed, a shard of the dragon god's wrathful nature infused you, resulting in a violent temper, strange apocalyptic dreams, an obsession with dragon hunting, or some other touch of his influence.

Choose two attribute boosts. One must be to Strength or Charisma, and one is a free attribute boost.

You're trained in the Athletics skill and the Dragon Lore skill. You gain the Titan Wrestler skill feat.
