In addition to the "curse enhancer", advancements in other abilities were also significant.
All of his low and mid-range skills have seen a significant improvement and his skills as a Puppet have also seen positive advancements.
Now he no longer needs to injure himself to attack or curse someone in battle, before, he used the blood of the Kumogakure group to create Voodoo dolls, which took time, something he wouldn't have in a truly fierce battle.
Now he could do it directly without harming himself, although of course, if he injured himself he could increase the power of the curse.
Furthermore, whereas previously this ability was limited to direct damage, now he could use curses while injuring himself. He could, for example, banish, bind or put someone to sleep by sacrificing part of his body, of course, he would heal himself.
Besides, he doesn't need blood to do this, a simple visual connection is enough. Of course, a medium like blood increases the power of the curse.
It's a game of balance, the stronger the connection and the more you're willing to sacrifice, the stronger the curses become. It's no coincidence that the series was originally called Cursed Artifact.
His ability to transform others also evolved, previously, he could only transform targets into Puppets, and that was only if they allowed it or were unable to resist.
This time, however, the transfiguration curse underwent a beneficial advancement, he could emit a silent scream that could transform targets into harmless animals, losing most of their abilities while in this form.
Unfortunately, it can only affect one entity at a time, otherwise, it would be really interesting to see thousands of ninjas transforming into chickens and rabbits.
This curse could affect not only living beings, but also objects and this ability could also be transferred between connected bodies, that is, if he used the Raikage's Voodoo doll, he could transform it into a chicken and the Raikage would suffer the same fate.
Another point is that he no longer needs the Tenebrous World to answer prayers, if someone prays to him within a certain range, he could still respond.
Sure, he needs a proper honorific name for "Jugo" with five lines instead of 3, but he has no interest in doing that, he doesn't need his own followers in this world, so the Tenebrous World is enough for him.
But the joy slowly faded, because Jugo discovered the method for advancing the sequel, Ancient Curse.
He needs an ancient and malevolent item capable of containing angelic power. This item will become the core of his complete mythical creature form.
Jugo's lips trembled fiercely. Finding Madara's corpse with the pseudo-six paths' power wasn't enough, now he needed to find an item that could restrain his angelic form?
Not just any item, but an ancient and evil one. This means he couldn't simply create it, it must already exist and possess the characteristic of being "evil" If that were all, he could find a way to deal with it, but what item in this world could serve as the core for an Angel?!
An angel's power borders on divinity, few items could possess that kind of property. The only one he could think of immediately was the Gedo Mazo, but would the Juubi have that "evil" aspect?
In Jugo's opinion, no. That's because this evil aspect is based on the world of LOTM, meaning it needs to be truly evil, the kind that can destroy, corrupt or curse simply by existing, and the Gedo Mazo doesn't fit that description.
This left Jugo extremely frustrated for a moment, he knew of some items that could be considered evil in the world of Naruto, such as the Gokuraku no Hako (Box of Supreme Happiness).
But even that doesn't seem to withstand the power of an Angel, perhaps only the power of a Saint, but an Angel? Jugo finds it difficult to believe, even so it's a good start, it's an item that is both ancient and evil.
Even so, Jugo didn't put all the eggs in the same basket, he started thinking about other compatible items, but soon his thinking began to diverge a little.
What if the item was old, but not evil?
If Jugo were to place it in the Tenebrous World for long enough, any item would have the potential to become "evil" and he could even accelerate the process with his current control of the Sephirah. This opened up a whole new range of possibilities.
Jugo shook his head, ready to return to the village and think about it calmly, but when he left the cave and looked up, his eyes were fixed on the night sky, more specifically, on the moon.
Looking at that bright orb in the sky, Jugo's eyes slowly widened, he remembered something.
Not Kaguya's seal, that would be of no use to him now, instead, his thoughts turned to the giant Tenseigan.
Countless Byakugan giving rise to a massive Tenseigan, that thing... should be able to hold its mythical creature form, right?
Unconsciously, Jugo licked his lips, a smile slowly forming on his face.
The next moment, he raised an arm and a white snake emerged from it. The snake perfectly transformed into a Jugo's Snake Clone. The next moment, the clone transformed into Wraith. Jugo grabbed a kunai and the snake clone possessed the kunai.
It wasn't a simple possession like the one made possible by Wraith and Puppet's powers, but a fusion in the style of the Disciple of Silence, that simple kunai transformed into a cursed object, its strength increasing tremendously.
An enormous amount of senjutsu chakra began to fill the kunai, to the point of almost breaking it, if it weren't for the snake clone's possession, it would have already broken. A thin layer of wind covered the kunai, as thin as a hair, yet the buzzing sound made by the extremely compacted wind chakra was tremendous, the kunai itself vibrated at a high frequency.
The senjutsu chakra transformed into an extremely sharp wind, Jugo knew that this simple kunai could now cut a Bijuu in two pieces.
Smiling, he pulled his arm back and in the next moment, threw the kunai upwards, directly towards the moon.
As for finding the portal? Sorry, it would take too long and he prefers to be more direct. Even if Jugo missed the moon by a little, the kunai itself was possessed and could easily alter its trajectory, after all, his ability to control objects, acquired when he became Puppet, only grew stronger, it was like a guided missile. Target? The moon.
