This was amazing for people who had {Auto}. But it also meant that if you did not have an {Auto} state, {Regen} would be useless. That was why Dearest didn't try to use it on the corpses outside. It wasn't that he didn't want to, it was that he couldn't.
{Regen}'s only weaknesses were that it did not ease pain and that it required {Auto}. And my {Kindred} just casually broke the rules of his own {Fate}!
If he could summon {Regen} without the {Auto}, didn't that mean he could heal any injury, no matter how severe? If the same applied to {Rewind}'s other abilities, wouldn't he be able to bring someone back from the brink of death?
{Rewind} would be without limitations! It made no sense!
'Dearest! How absurd! You are breaking common sense again! I am beginning to understand why Bella keeps calling you a cheater!'
'Haha, please forgive me for this one-time everyone, {Rewind} is kind of lame compared to Siren's {Fates}. Let me power up a bit too.'
