I think you missunderstand. The reason it's true damage is because it's a separate instance of damage based on the damage already dealt. So it's already reduced by the opponent's MR. It's the same thing to when you attack a turret with an Earth Dragon Buff.

With this new passive he amps magic damage done... just like his current passive actually. The only difference is that it amps it a lot less until the opponent gets 150+MR but to compensate his ult now applies it to everyone.
