New Champion Death Passive Concept
This is kind of like a combination between Aatrox's passive and a reverse of Kindred passive.
When the champion is killed by an enemy champion they die, like normal, but when they respawn at the fountain they gain a permanent stat boost Of + (undertermined). This can only occur once every 180 seconds.
Pretty simple really, and it can be applied to any type role. Give an AD, AP, Attack Speed, Crit strike chance, movement speed, HP, Hp5, % HP, Mana, Mp5, % Mana, Armor, Armor Pen., Magic Resist, Magic Pen, CDR, maybe even gold or exp .. anything.
The player may want to try and get this passive stacking early, but the drawback would be that they would be giving up first blood to the enemy team, which I bet they would be happy to take. Or they may avoid killing you in order to deny you the passive stack. That could be interesting.
Limiting the kill condition to enemy champions will prevent suicide to towers and executions by minions or monsters. Putting a cooldown on the passive will also prevent constant feeding for stacks.
It would also be wise for the player of this champion to keep in mind that giving kills to the enemy will essentially make them stronger as well. Being careful to not feed an already well fed opponent is definitely something to consider. Dying to an enemy who is behind the rest of their team can also help to make the enemy team stronger all together.
**I want to clarify, it is not my goal to make the playstyle of this champion out to be "Who should I let kill me next?" but I want a death to ultimately become a minor benefit to you as well. When it comes to balancing, I don't want the reward of your death to become so strong that you WANT to die. Instead, I want your death to keep you from becoming irrelevant. **
