The concept is fun
Skill might be interressing to watch

But some point need to be corrected

like a clone skill... no, might harsh on battlefield to see your target when surrounded by your clone
And potency must be rework

1500 potency ?!
Please even the black mage cannot approach half of these at his peak

And last but not least
Evolutive weapon ?
No these is the relic
Any other weapon are set and that's all
You might have additionnal buff that give you boost but your weapon cannot change
