[Of course, the effect can be mystic and reality bending, but will be contained within the limit according to your personal overall power by the curse law of 'Danger for Reward' even if you make it absurd, so better make your effect carefully. If your extra effect can be accepted as it is, the general 'set' power and effect boost you get by maintaining your oath will be stronger.]
'Gotcha.'
Aeron focused and kept his flame arrow pulled, but didn't release it. In his source region, he started writing the oath.
< I will always use my bow when attacking enemies in a loop order of three precise steps. >
However, Aeron suddenly stopped as he got an idea.
'What if i restrict it to this particular Phantom Ability instead of bows in general? Yep, this is good.'
[You need a name for this Phantom Ability you created.]
'Hmm...that's it. I got the name. Also, might as well modify the ability a bit to make it suitable to my oath,' Aeron nodded with a grin. 'This is better.'
Lapis chuckled. [Yep. You got it. Glad I didn't have to tell you that.]
Aeron internally rolled his eyes. He kept his bow conjured and pulled an arrow for two seconds before he dispersed the ability and used it again.
He pulled a FlameArrow and released it.
*Boom*
He pulled another one and released it.
*Booom*
'Last.'
*Boooom*
'And it's name is...Flamehunt Rambe.'
Aeron quickly wrote his cursed oath bound to the ability while a notification of Phantom Spark rang.
[Congratulations. You have created a C-rank Phantom Ability—Flamehunt Rambe.]
When he finished the oath, another notification rang.
[Flamehunt Rambe has become Oath Bound.]
*Boom* *Boom* *Boom*
'My current speed is pulling 1 arrow every 1.5 seconds. The last one is taking me 2 seconds,' Aeron narrowed his eyes. The 3rd arrow pull required a strong and precise enough pull of the string that the bow's both ends must only have a distance of 1 centimeter between them.
The pull also required him to use Fortify of 10 x physical boost in his arms. It cost him 1000 curse energy.
Each arrow broke the sound barrier, and its speed generated extra kinetic power, increasing the damage even more, especially since flame explore and general explosive shockwave are contained within 1-meter radius upon impact. This increased the damage in that 1-meter radius bubble to an extra level.
'If I had this Phantom Ability against that C-rank Samurai Haunt, I would've insta-killed him,' Aeron grinned.
[True, but there are more dangerous and tricky C-rank Haunts with various powers. The Samurai had curse energy on a higher spectrum of C-rank, but its abilities were not as much. You'll understand when you encounter more Haunts in Dark Ruins or when this city gets attacked next time.]
[Also, you can practice until you can pull the arrows every second without mistake here. But after that, we'll go join a Guild so we can enter a Dark Ruin. Practicing there is better, and you can make more makeshift Phantom Abilities there while gaining experience.]
[Phantom Hunters usually do that and then come to the training room to solidify their experience and improve their Phantom Abilities.]
'Good idea. I only took 30 minutes to create this Phantom Ability, so I can make something more of this level anytime now that I know how the basic works,' Aeron nodded and began shooting arrows. 'It's only a matter of how to efficiently use my everything in imaginative creations.'
'I'll practice for one hour and create some new types of Arrows. For example, I can Transmute spirit energy to Wood, so how about Vine Arrow that produces vines around the target upon impact and my trigger?'
'How about a Shield Arrow to create a humanoid-sized stone wall upon impact?' Aeron grinned. 'The more Enchanted the arrow with curse energy, the stronger its effects.'
Lapis was surprised.
[Different types of arrows with effects, eh? Not bad. Those simple effects should be easy to create since you got 100% proficiency in the first level of all basics.]
Aeron's eyes glinted. 'I'll make those Arrows and refine them in the next hour. After that, we'll go join a guild. If I can get Mystic resources like some exotic magical wooden materials from Dark Ruins, I can scan, study, and conjure them for suitable bows for different types of arrows.'
[That's...you are creating a skill tree of Archer or what?]
'I'm doing just that and will finish it today as long as things go as planned,' Aeron smiled with shining eyes, thrilled even. 'Let's start.'
...
One hour later, Aeron left the Phantom Tower.
"Selina mentioned that Star Horn guild. Should we try there?"
[Star Horn Guild is one of the five Pillar Guilds in the city...but we can try there. Let's go. It's better if we join one of the five Pillars, but I don't know their criteria and tests. It's up to you.]
'Gotcha.'
