Rework Conqueror so that the in-combat timer procs on only champions
That way the Irelia or Jax won't cheese you by stacking it on minions then jumps on you with physical+magic+true damage and erases you from existence.
Maybe do the same to Grasp
Or just delet it rework it to an entirely new design because it's only them who uses Conqueror and everyone else found their own keystone by now
