  • Non-canonically, fire suppresses their regeneration; burns are extremely difficult to regenerate for krogan.
  • Canonically, krogan have two hearts. In SoR, they have a third, a two-valve structure located at the bottom of the body cavity. Hitting all three hearts is the only real way to ensure death on a krogan in a knife-fight.
