I should probably phrase that part of the passive a lot better. What I meant to say is that the damage Vladimir deals to his victims is converted into a meter, so the cap hits when he deals 30% of their maximum health in damage (after reductions). You're right that every 0.3% of their maximum health in damage that you deal counts as a stack. The stacks increase in the following way: suppose one stack has a base value of x. One third of the way through, the value of subsequent stacks doubles, so every next stack is worth 2x. Two thirds of the way through, the value doubles again, so every next stack is worth 4x. This doesn't retroactively increase the value of previous stacks, so if the first third had a value of X the sum of thirds would be X + 2X + 4X = 7X. Because stacks don't increase in value on minions, the maximum damage/healing you can have on them is X + X + X = 3X. This sounds a mite overly complicated, but I want it to work like this so that the damage/healing doesn't spike at fixed values, but rather starts to scale a lot better.
