A 99% power weakening would mean that his target, who got debuffed, would only be able to display 1% of their combat power.
Of course, that was merely the limit of the Great Weakening superpower and wasn't the minimum. The percentage of Great Weakening would be dependent on the gap between his target and himself.
Moreover, it didn't seem to be useful to those Starlight rank powerhouses with a Principle-level fragment of a certain Universal Law.
The Great Weakening superpower could at most be considered Authority-level, as its effects could achieve it, but it wasn't even a true authority yet. It didn't even reach the minimum threshold for 0.001% Authority.
For a powerhouse at Zayne's rank, it was better than nothing. But for Arthur and Green, receiving a second viral superpower would greatly increase their power rank.
Anyway, Zayne didn't plan to rely on Main World Terra to improve his power rank since his main source of income was the Doomsday Life Simulation.
