The power that could end the battle immediately isn't beneficial for his current aims, it isn't like he wanted to avoid using such powers, it's just that he prefers to follow the limits he had placed upon himself in heart's value.
He decided to only use those overpowered unique skills and traits in times when he is in a pinch or fighting someone who couldn't be overcome simply by using techniques and external factors alone.
He isn't an idiot to push things to the point where he might truly die.
Kanzen designated that the unique skills and traits of his are only to be used as trump cards.
He could still recall how pitiful the first goblin that he had killed using his unique skill on it out of curiosity.
The type of power contained within his unique skill and his offensive trait is something he himself didn't want to experience or face head-on, because of how vicious, terrible, powerful and traumatizing those powers were it stole the purpose of his adventure.
He also didn't want for people to begin trying to come up with countermeasures against his powers.
So, trying to limit his usage of such power earlier on is a good way to prevent himself from relying on such power too much.
…
"Big sis Tina, it seems like nature really does possess a will of its own, from now on, it wouldn't allow me to always lend its powers just like earlier, this is the only time I am allowed to wield its power freely without restraints." After using natures' wrath for the first time Kanzen senses nature's true will, not the item he held in his hand but the very ego of nature.
He could sense that nature's ego had treated him like a little brother of sorts, it instantly allowed him to use its power earlier using the staff as a medium for both conjuring its power and to communicate with it.
Hearing Kanzen's words, Tina wasn't surprised in the slightest, just as her previous origin Starlight, the nature is also a conceptual entity that possessed an ego of its own.
[How would it take before you could unleash something on this level of power again?]
"Based on my calculations, this world's natural mana is dense, but not dense enough to the point that it can fill up the container in a short time. I probably need to wait for a month before I could unleash something on this level again, also the [Nature Will's] seems to have evolved due to the intervention of this world's nature. I need to analyze and confirm what changes have occurred."
The earlier performance is due to the nature giving him a hand in using the item skill.
Now he needed to gather natural mana to cast the skill [Nature's Wrath]
However, after the item evolved he now needed to either replace the natural mana container or wait until it gathered enough natural mana of its own from the surroundings.
The only restriction in this is the number of times he could use the skill [Nature's Wrath]
The staff couldn't handle the continuous release of such power, so he is limited in using the power of nature once every month to avoid destroying the expensive weapon.
He then relayed these details to Tina.
[That's reasonable, it isn't like you could always use such devastating attacks, even if you were to use your isolation domain technique the changes in the natural mana around the vicinity could cause irreversible consequences for the nearby inhabitants. Monsters might begin manifesting out of thin air if the natural mana ended up too dense]
Hearing Tina's deduction Kanzen nodded in understanding before continuing.
"Yeah, this power is also useless when I am with others, as I am the only one who'll be unscratched after activating its power, it isn't like fella know the term no friendly fire." Kanzen muttered, before touching the tick transparent membrane that has the shape of a cube surrounding him trying to keep him safe.
A look of astonishment can be seen on his inquisitive eyes that began analyzing the very structure of the transparent membrane presented before him.
…
The devastation brought by the [Nature's Wrath] began to calm down, the previously land filled with goblins were swept cleanly not even the high graded equipment was spared from nature's wrath.
"*Sigh* those equipment could have fetched me some money." Kanzen said in a dejected tone.
[Your line of thought seems to have developed in a strange direction] Tina interjects in a teasing tone.
"Haha haha, that was just a joke, don't mind it big sis, Tina."
[No you misunderstand, Kanzen that was the right mindset in this world, it just felt strange to our perspective because of our actions too far. Normally, adventures would loot the stuff of the creatures they have slayed. So, it's safe to say looting corpses isn't inappropriate, it's just that ever since we arrived in this reality you really never once tried looting something from the creatures you have defeated. The only exception to this is their energy core that is automatically being sent into the inventory the moment you killed the owner] Tina explained.
"You're probably right, now that I remembered it the high-class adventures in the anime are said to have gained bountiful rewards if a loot apart from the energy core is left behind by the slain monsters. It appears to me that I relied too much on the system functions that I skip the basics, my common sense in this reality seems to be lacking."
[Either way it isn't like we couldn't do a thing about it, better relax and let things developed in their own naturally, from now on, you can start by learning the right steps to be followed in butchering carcasses] Tina advise, she was also concerned about Kanzen's common sense developing in a different direction, being unique might cause people to take advantage of him or shrugged him. She didn't want Kanzen to fall in any of those categories.
"Unfortunately, no corpses were left behind… haha haha!"
Kanzen was forced to swallow his words when notice two strong vital signatures beginning to fluctuate strongly like a beating heart inside his domain.
Looking ahead, Kanzen's sight pierced through the tick smoke present, blocking the surroundings view.
His eyes were drawn to the figure of a gorgeous green skin middle age beauty and a handsome green skin man, surrounded by a strange membrane not too dissimilar to the one surrounding him except for the color.
His pseudo omniscient began working in overdrive as his mind started analyzing the membrane surrounding the Goblin King and Queen.
"It seems that fate really is on my side." Kanzen said, a wide grin started to spread on his face.
[Be careful, things don't seem to be as simple as you think] Tina reminded, her focused on the unconscious Goblin King and Queen.
Done with the analysis of the barriers surrounding the two monsters, Kanzen's expression turned weary.
"Those barriers don't seem like your everyday common barrier."
[Isn't that very obvious, dumbass! How can a common barrier block the power of the <
