I'm gonna come up with some abilities for this
The sword of creation
Recently forged by the Collector, made specifically to harness the power of the crystal in the perfect sword, it has several similarities to other weapons of extreme power like the terraprisma and zenith
Because of this the sword can summon copies of itself to fly at opponents and stay at his side to attack any enemies around him
When it is wielded by someone who doesn't have the crystal they can either use a fraction of it's power Or it simply functions as a regular sword
When exposed to the crystal of creation it can morph into different shapes, for example the blade can shrink to be used for quicker but weaker attacks
Or it can become a battle axe for stronger slower attacks
This could be used if you're fighting the collector with this sword
