Amongst werewolves there were pure-blood werewolves, these were people like Duke Hail, Lara, and Michael who come from an ancient lineage of werewolves.
Once born, they automatically inherit one of the five ancestral powers. Pure blood werewolves could also transform at all times, and they weren't influenced by the full moon.
Then there were cursed werewolves like Damon, people granted the power through magic. These people become slaves to the full moon, unable to harness their full power until then, and even when they can harness their full powers, they struggle for control.
People like him would have to work hard to gain control over his power.
Unlike pure-blood werewolves, he needed another ritual to gain the blood demon power even after gaining the werewolf curse. Apart from that, cursed werewolves like Damon were generally weaker.
Bam!
