Just a little graph thing I found out

If mordekaiser gets something like vayne ghost, the game doesnt add any true damage dealt by the ghost to the "true dmg dealt" bar in the post game graphs for mordekaiser. I'm not sure if it even counts it at all under total damage dealt by mordekaiser. This might make the mordekaiser player feel like he did less damage overall than he really did in a given game.
