2in1 Champion Concept: Rea'Korx
Rea'Korx are actually 2 different beings. Rea is female and Korx is male.
He is melee and she is range (like personal support). She barely has any armor or magic resist, but he does. And since she is very squishy she has some serious survival abilities.
Since Rea and Korx share same hp if he die she will die and if she die.. he will die. If you do 200 dmg to Korx and he had 2000 hp after your 200 they both will have 1800.
Rea doesnt do dmg with basic attack or any skills (she is the good he is the evil). Her basic attack heals instead of doin damage and of course she can focus only on ally champions ( i guess she will have much slower attack speed than Korx, which of course can increase if you get attack speed.
Note: Rea and Korx must be together to heal in base.
Passive :
Since Rea basically does nothing but try to survive i decided their passive must be something that will keep them together. When Korx is in Rea's range they both receive the other one's strenghts, she gains % attack speed and he % lifesteal.
Q/
Korx dashes forward leaving trace of (fire or something) dealing dmg to enemies for ? seconds.
ALT+Q/
Rea heals herself for % max hp. (also heals Korx since he has same hp as her)
W/
Korx gains % attack speed and % movement speed for ? seconds.
ALT+W/
Rea receives barrier around her that blocks all incoming abilities (basic attacks too) for the same duration.
E/
Korx jumps to target area to damage and stun enemies inside the area for 1 second .
ALT+E/
Rea becomes invisible and gain % movement speed for 1 second .
R/ and ALT+R/ (unlimited range)
So my idea for the ult is to unite them into 1 being - Rea'Korx the only thing they receive is both of their hp for example if both of them have 2000 Rea'Korx will be with 4000 for few seconds but only with Korx's abilities (since she doesnt hit).
The difference between R/ and ALT+R/ is where to unite them, because she might be bot supporting ADC and he gank top for example and if you press R/ it will unite them to Korx on top , if ALT+R/ on bot to Rea.
Such champion is very hard to balance, so everyone is welcome to help building it if you like the idea of course : ) Also i decided that Rea's abilities shouldnt be connected with him because of their passive and i tought they will be too OP, but if you decide to leave her to safe place and dont receive their passive Korx should be fairly weaker, so im still hoping for better idea for his part of the passive, they must mostly stick together because she is the quick way to kill Rea'Korx. But i guess dash and jump ability are decent combo for Korx and if Rea isnt around he can use them to escape if things get ugly.
Also considering that it will be not that easy champion to play since u have to use both of them at the same time , they seem fine to me :D
After ultimate ends they split on 50% of current hp, also both of their passives work while ultimate last . At first Rea seems kinda useless but when you think of her basic attack hitting you while you fight even without her passive attack speed is decent. (of course she must hit really slow or provide low amounts of heal, so she can be around Korx most of the time to get passive buff to be more effective)
Rea can also buy items while Korx is still on his lane or in jungle, but as i said they must be together in order to heal in base. I was also thinking that Rea shouldnt be able to absorb exp, because you can just 2 lanes at start and go lvl 6 while people are still lvl 4 :D
