Soul weapon was like a materialization of a person's personality, not all people had the ability to form soul weapon, it was something that only certain person could do, probably about one in a hundred person could form a fragment soul weapon and one in a thousand can actually form a soul weapon.
That wasn't the limit of soul weapon forming, one in a million could also form an extra soul weapon fragment and as for two soul weapon only one in hundred million could achieve such feats.
A soul weapons strength couldn't be compared with an ordinary weapon no matter how weak a soul weapon is it could fetch for millions, yes soul weapon could be sold true the act of soul injection if the owner wishes to sell a soul weapon bit could be possible by injecting it directly into the soul of another. Apart from that there are also other method used by clans to give the soul weapons of elders who are dead or no longer able to battle to younger generation or to keep it as treasures.
But the difference between the strength of the weapon in the original owner and the new owner could get vast depending on talent, nature and understanding of the new wielder after all a soul weapon is unique to the owner itself.
Soul weapon although are powerful but not equal, they are divided into different grade, From weakest to strongest, spirit grade, earth grade, heaven grade, Astral grade and true essence grade.
The difference in each grade increase exponentially as ten spirit grade woul be equal to one earth grade, hundred earth grade could be equal to some heaven grade, Two hundred heaven grade could be equal to one Astral grade and one thousand Astral grade could also be equal to one true essence grade. Legends also had it that there is an higher level grade that the true essence grade, it could all just be fairytales alongside the seven godly weapons.
"So you're saying that Halberd was Astral grade soul weapon awesome, well the same could be said for mine, I was a peerless genius back at him after all" Ark couldn't help but brag in front of Silver it was a collision between two genius of their different family.
Two days later close to the edge of the forest two figure stood face off against a grey furred tiger, it was twice the size of a full grown regular tiger, it had blue stripes and a sharp pointed horn on it's head.
"A thunder cat, how troublesome!" Silver said looking at the overgrown tiger in front of him, of course it wasn't a problem for him but thunder cats had a strange ability, it's like a triggered phenomenon after death , all it's spiritual energy after death is condensed into a single bolt of lightning that's capable of instantly killing an expert fighter.
The power of the lightning depends on how many cores the spirit beasts has condensed, Spirit beast gain throne spirit energy by forming cores, it takes at least two cores to become a true Spirit beast, Four cores to become an Elemental spirit beast, an extra two cores to become a mid grade Elemental beast, an extra four cores to be come an high ranking elemental beast, it takes am extra five cores to become a peak elemental spirit beast, a peak Elemental beast could probably wipe out an entire one star clan or family and do significant damage to a two star clan if not wipe out some.
The Thunder cat in front of them was probably a high Elemental spirit beast with at least twelve cores and the condensed Spiritual energy could definitely cause some damage. "Allow me to fight this foe for you, I know how to handle this kind of situations."Ark said as immediately a golden hue surrounded Ark as his spiritual energy sky rocketed.
"So he uses some kind of strength buffing technique, interesting."Silversaid as he watched the ground at Arks feet sank at every step he took. The Thunder cat dashed at Ark using one of its special skill known as lightning trail, Silver eyes widened as he saw the tiger immediately slowed down as it came close to Ark despite still using the speed skill it was as if it was walking.
