Every third strike Vayne does % max LP true damage to the team.
This is further proved by the Vayne Theorem:
I hope Riot can fix this small tooltip error soon. I never notice it until I'm in game, and by then, it's too late.
This is the truest thing I have ever seen.
Ahh, the good old "Law Of Shaco" 
Every single time.
100% true
Vayne is the bane of this game it's hard to tame that lame vayne but with swain it is very K... n.
That' s a common oversight sadly, like in the Yasuo case where the wind barrier also deals tilt damage when it manages to block a projectile.
This has to be untrue for somebody.
But I never see those people. And this has always proven 100% positive.
So using this logic... would that mean that the opposing team in this instance must be a figment of the imagination? Because they exist outside the paradigm of this formula.
But... wait...
Perhaps they aren't just a figment. Perhaps having a Vayne in your game automatically opens up a wormhole into an alternate dimension with opposite rules? A dimension where instead, having a Vayne on your team means that you will have a challenger smurf and having a Vayne on the other team means that they will feed to no end? And we are simply unaware of which universe we belong to because the only way to test the theory is to attempt it and we are far too afraid to try such a thing? That by doing so we have officially sorted ourselves into a universe separate from the other - that this thread is not present in the other but replaced by one that says "Every third strike Vayne does % max LP true damage to the enemy team"?
LP damage...seriously?
Upvoted.
Same thing with 
.....
I'm preeeety sure the LP loss is static.
Otherwise, true.
Should be ap/ad damage and not true damage. I hate that op shiz.
