The debuff potions concocted by Sebastian Slughorn posed a significant threat to some of Edinburgh's most renowned Rankers.
They were designed to inflict targeted debuffs on Rankers who had been exposed to the Myriad Potioner's specially crafted concoctions.
Sebastian had prepared these potions in advance. After disposing of Sebastian and commandeering Brewmaster's Bounty's cargo, Eren incinerated the ship to eliminate all traces of his possession of such potent potions.
Now, Eren saw fit to utilize these potions, which spelled trouble for Edinburgh's Rankers.
Unlike Sebastian who had used alchemy dolls to deploy his potions, Eren decided to use his shadow-element powers to achieve greater efficiency in potion deployment and effectiveness.
Eren had also assimilated with Levine's Elemental Attainments using the Sin of Lust Ability. He used Levine's way of teleporting potions freely anywhere within a certain range, allowing him to insert the potion vials into the shadowy creatures he had made using an area-of-effect wide scale spell.
One could say that Eren had fused together the things he had learned from Levine and Sebastian together before finally creating something different out of them using his multi-element compatibility as a foundation. This way, which was now unique to Eren, allowed him to make use of Sebastian's Ability with even more precision than him. It also made it easy for him to catch his opponents off guard without having to use the alchemy dolls.
Of course, Eren could not have custom-made debuff potions for everyone that was present on the opposing side. However, he did not solely rely on Sebastian's potions that he had secretly seized from Brewmaster's Bounty.
He had kept Sebastian's work going during the last 9 years, using his Ranking Class as a Potion Expert to its fullest to concoct more targeted debuff potions for as many Rankers he knew from both Edinburgh and Layos' side. Plus, he could always create debuff potions on the fly using his Myriad Potionneering Ability.
Since these ethereal concoctions had been made hastily, the debuff they would produce was bound to be lesser in comparison to the ones he had prepared in advance. However, as long as the debuff worked even for a short time, Eren knew it was enough for his allies to give a strategic advantage.
Especially when so many debuff potions had been deployed in such a unique way, taking the opponents by surprise.
Eren was able to summon the custom-made debuff potions that he had prepared in advance for around 65% of the Rankers who stood against him, including Adam Stone. The potency of these potions prepared in advance by Sebastian himself was so much that the Rankers affected by them would lose almost all of their powers or would be unable to tap into them for a short time.
This window was enough for Eren and his allies to slaughter them quickly.
The remaining 35% of the debuff potions had been concocted by Eren on the fly using his Myriad Potioneering Ability. It did not have that much potency in casting debuffs for Master Rankers included in the enemy group. But it severely affected the Rankers below the B-Rank, effectively robbing them of their movements and access to mana for a few moments.
Those moments of weakness were now about to decide their fate.

'He… he can use shadow-element spells too? This was never mentioned. This is un fucking be…'
Adam Stone muttered in disbelief as he watched the rapid and unexpected events unfold before him. They occurred so swiftly that he couldn't react defensively.
A shadow behind him cast a kind of pseudo domain that affected him. This pseudo domain acted like a debuff and severed his connection to his own mana core, rendering him incapable of casting spells.
Even his Elemental Attainments were affected by the debuff, as if some strange interference was preventing him from interacting with the world. With this abrupt disconnection, the excited Berserker could no longer sustain his Movement Spell, causing him to come to an abrupt halt and nearly lose his balance.
Before Adam could regain his composure and find his footing, his perspective shifted abruptly. He discovered himself staring at the ground, his face forcefully pressed into it, mud and blood obscuring his vision.
In mere moments, Grandmaster Adam realized that his head had been severed by the very Master Ranker he had insulted just moments ago. He never even had the chance to unleash his Berserker powers against Eren, dying in a manner one might describe as sudden and unremarkable.
In the next moment, the Berserker's eyes turned lifeless while his own torso was bathing his head in streams of warm blood. One could see the expressions of shock and injustice still etched over his face if they were to pick his severe head from the ground.
Eren had timed his attacks with the debuff perfectly. He had to say that Unlimited Weapon Works and Hero's Heart were one of the most low-key yet highly effective Abilities he had received from his trip to the Sansara World.
These Abilities allowed him to stack the effects of his various powers together, enabling him to kill a Grandmaster Ranker as well within such a short time. It was nothing short of a miracle, in this case an unexpected nightmare, for the remaining Rankers of Anfang that Eren had managed to kill a Grandmaster Ranker.
"That's one down."
Eren turned around and muttered to himself while gazing at the lifeless body of the Grandmaster Ranker. While he would typically celebrate another Grandmaster kill, the time constraints didn't permit such revelry.
Eren vanished from his spot, conjuring a series of elemental spells around him. He deployed his Master Rank powers on the opposing Rankers who had come to confront him, systematically eliminating them.
Eren's allies found it easier to handle these 350 Rankers, despite the substantial numerical advantage held by the enemy side.
Eren's targeted debuff potions proved to be invaluable, enabling Naya, Alephee, Ivor, and the others to dispatch the enemy Rankers with ease.
