A sort of champion i hope riot one day will add

Someone who can split into 2 and while your half is running around your HP is cut in half but when reunited its back to the portion of HP you had united unless you or your half took damage ofc. So you could make your half clear wards , check bushes , push a lane while you recall and buy something from the shop etc. Then the ultimate would simply be you teleporting to the half's location if its activated. But the majority of the kit wouldn't necessarily be powerful at all unless your whole then your at your strongest. Split into two and your power is halved but you have more opportunities at hand to do different things.

So lets say you wanna buy something at the shop? okay but you lose half of your HP until your half returns back to you , or you can switch priorities and ult back to your half in lane from the shop but then you have no ultimate.. see it could be somewhat balanced.. the overall kit just cannot contain too much power itself. Ideally i see this make-believe champ as a mid mage.

Both can do a tiny bit of this already but not full scale only temporary stuff not a legit 2nd half that shares your HP and lasts forever. Its a kit nobody has ever seen before and adds something new and interesting.
