Your power's scope has been increased. You now have the ability to summon up to seven other versions of yourself to fight alongside you. Your coordination with one another is perfect and they are absolutely loyal to you. The other versions can be as powerful as whatever your strongest form has been, but as you get stronger so do the scope of your possible versions you can summon.
If one of them dies you may resummon them to revive them, and if they survive past your death, one of them will receive your memories and soul and perfectly merge with you to resurrect you. This will not cause you any changes, it'll just cause them to be desummoned and you summoning yourself back to life in their place, and they can be recalled back as soon as you’re alive again.
This power can now also be extended unto others and objects, allowing you to alter them into different versions of themselves and/or summon up to seven copies of them, however you choose whether their copies are loyal to you or the one you copied from, and you choose whether they can revive through their copies or not. You can over time increase the amount of copies you can summon.
