[True, and that's what makes it even sadder.]
The system said, dishing out an absolute comeback, and Ryuk's expression plummeted.
[Hurricane Energy doesn't just let you poof out techniques just because you can feel them.]
'I can poof out a Void Vortex though?'
[Yes. But that's because you have a Void Grimoire, which is present in your Echo Library. You already have the source energy of Void Vortex, which is Void Apex Energy. That's why you can "poof" it.]
[Throne Shift is a Knullic skill that uses Abyssal Energy.]
[Do you have an Abyssal Energy Grimoire in your Echo Library?] the system asked, which finally helped him grasp the logic.
'So I need an Abyssal Energy source to activate an Abyssal Energy skill, huh?'
[Yes… fool.] It said, not forgetting to slam him once more.
'Tsk. This is more complicated than I thought.'
[It is. And that's why maybe you should have thought twice before flushing your Knull bloodline.]
It rubbed, to which Ryuk merely shrugged off.
