Intelligence: Extraordinary Genius
Cecilus is a monster in terms of combat, in his early teens, he single-handedly
slaughtered an entire army that was sent to kill Vincent Vollachia.
[8] His swordsmanship is far beyond human limits, even as a child his skill was unfathomably superior to his own father's,
who trained his entire life in an attempt to reach the Heavenly Sword,
[25] slayed numerous people, learned from many schools of martial arts, absorbed and combined their techniques, all in order to culminate an ultimate sword-flash– which Cecilus considers to be a
flashy display with no actual usefulness.
[14]
By watching
Al fight just a single time, he was able to correctly guess that he possessed an Authority and
what that Authority does through sheer intuition,
[13] and his intuition also correctly informed him that
killing too many Zombies would be a bad idea.
[19] He is a transcendant being that stands at the top of the Nine Divine Generals, and his skill stands upon the steps to the Heavenly Sword. As a child he single-handedly defeated every soldier in a Vollachian Fortress with just his bare-hands,
all while ensuring he didn't kill anyone.
[16] Cecilus possesses a perfect memory–
he never forgets a place or object he has seen before.
[4] He was also able to weave through a rain of
invisible sniper-fire by sheer guesswork,
[13] and is
said to possess the talent[33] to reach
Reid Astrea's level of skill.
Cecilus' brain possesses incredible processing power, he is
constantly taking in information from his surroundings in order to grasp the location of everyone and everything nearby,
[4] and his analysis of physicality and behaviour allows him to accurately predict the location of everyone in the vicinity without focusing on them. His mastery of the Flow Method allows him to
actively control each and every one of his senses,
[4] as well as accelerate his own thoughts in order to
process the world in extreme slow-motion;
[4] such that in the middle of avoiding a flurry of deadly projectiles, he was able to mull over his feelings regarding the current battle,
cause a second Cecilus to be born from his accelerated thoughts,
[4] conversate with the second Cecilus, and then battle with the second Cecilus to determine which
will return to regular time as the true Cecilus.
[4] His mental processing even allowed him to, upon wielding a sword for the very first time, train with the blade for days upon days within his mind,
swinging it hundreds of millions of times, all within a fraction of a second in reality,
[4] and then utilize the fruits of his efforts immediately in combat.
Cecilus
completely wiped the floor[40] with
Elsa Granhiert in single-combat, who has such incredible intuition that
even with her senses cut off by Shamak, she was able to
accurately aim at a target's vitals and avoid an attack that
blew away the entire room she was in,
[41] and her intuition also allowed her to counter or avoid any attack she has already seen,
even if performed in great numbers.
[30] He is stated to have martial prowess that rivals
Halibel and
Reinhard van Astrea, and
is described as Reinhard's equal.
[42]
His swordsmanship has also been compared to
Wilhelm van Astrea's at his peak,
[3] who was able to surpass
Theresia van Astrea, despite her flawless swordsmanship and battle instincts as the Sword Saint,
which couldn't be surpassed in a lifetime nor eternity.
[38] Theresia's ability to intuitively grasp her opponents most vulnerable point, and see white rays of battle which she need only trace to inevitably kill her opponent,
had no effect on Wilhelm[23], as his superior skill caused Theresia's predictive rays to be constantly severed.
After accepting the Purge King's offer and honing his skills for 3 years, Cecilus has surpassed himself and
reached the point of being just a single step away from[36] the
Heavenly Sword, the very pinnacle that all warriors strive to reach, yet most never even place a single step upon the path towards it.
[28] His swordsmanship has reached
Reinhard's level, who stands in a
dimension all on his own, incomparable to even those who could surpass previous Sword Saints,
[37] who themselves stand at a level that
cannot be reached in a lifetime or eternity of training.
