"Footnote: Foresight Solidification": When any puzzle possesses a foresight ability, that ability can be used without completing the puzzle by consuming double the Energy Points. The foresight ability is then permanently solidified and cannot be refreshed by any other means.
Before Angel read it, he had been thinking that solidifying a foresight ability seemed pointless.
After reading it, he realized he had been completely mistaken.
This "solidification" was indeed a negative effect. Once a foresight ability was solidified, there would be no way to reroll that ability through other means.
For mages who liked repeatedly rerolling abilities to make their combinations more fitting, this was absolutely detrimental.
But!
The positive effect brought by solidifying a foresight ability was equally astonishing!
There was no need to complete the puzzle. Through "Footnote: Foresight Solidification," one could use the foresight ability of an incomplete puzzle!
For example, the puzzle on the fifth page of Angel's spellbook was "Brand-Name Cat." It was currently incomplete, with only one-third of the puzzle finished.
Ordinarily, this puzzle was utterly meaningless to Angel before it was completed.
But with "Footnote: Foresight Solidification," he could skip the process of collecting all the pieces and directly use the foresight ability that Brand-Name Cat had already revealed: Elegant Socialite.
Although the effect of this ability was not much to speak of, that was merely Brand-Name Cat's limitation, not the limitation of "Footnote: Foresight Solidification"!
Just imagine it: you obtained a puzzle from a high-grade Demonic Beast, but because the illustration was incomplete, you could never use it. Yet with "Footnote: Foresight Solidification," you could bypass the puzzle's restrictions and use that Demonic Beast's ability.
Even if you could only use one ability... it was still better than having nothing.
It sounded as though this page merely let one use an ability
