Ainsley almost never tried to use her Asmodeus mode because she didn't really know how to use it.
The blood clan mode could be acquired because she had awakened her bloodline, and she also became a blood clan the moment she was resurrected.
But the case with Asmodeus' bloodline was not that simple.
Even if she did have an Asmodeus bloodline through the Sloan family's ancestor, and the Asmodeus avatar himself had already purified her bloodline to be exactly 1% purity instead of the less than 1% purity like before...
But Ainsley had never transformed into a hell demon derived from Asmodeus' demonic form.
Other people who had legendary bloodlines were all already the same race as that bloodline, so they didn't really need to transform her.
