Ainz power null resist

“[Twin Maximize Magic – Reali―”
Just as Ainz was about to cast a spell at Lupusregina, another bullet hit Ainz’s
arm and interrupted his spell.
“―Hah?”
Impossible!
Even if she had succeeded once by luck, she could not have interrupted his
spell twice in a row. CZ was far lower level than Ainz.
Could he have been unlucky enough to fail his resistance check twice in a row?
How unlikely were those odds? Or perhaps this was not bad luck, but certainty
― for instance, if his opponent was not CZ at all?

[...]

―No. There was no time to think about such pointless things. Only one thing
mattered. Could they completely shut down Ainz’s spellcasting, and could they
keep it up forever?
There were two kinds of special abilities in Yggdrasil. One kind had a cooldown
period after use. The other had a limited number of uses within a certain period.
There were also combinations of the two.
In general, the more powerful the ability, the longer the cooldown or the
fewer times it could be used. Ainz’s trump card ― [The Goal of All Life is Death]
― which could only be used once every 100 hours was just such an ability.
In that case, which type did CZ’s ability to interrupt Ainz’s spellcasting belong
to?
That move just now was very handy, but it did not seem to have a long
cooldown time. That would mean it was the use-limited type. However, he could
not tell how long it would take for her to recover her uses. All he could do was
hope that she could not recover them during the course of the battle after they
were depleted.

Ainz never went head-to-head with his opponents during PVP so Ainz had
little experience in dealing with commander-type opponents.
She could not have left the Eighth Floor and come here without my permission. That
would mean that she must have buffed the Doppelgangers before they came here. That
would mean she probably didn’t buff them too carefully — or no, is there a
Doppelganger of Aureole here?
