Lee took 0 damage from my ult ?

so I came in on this guy as A full build Evelynn, and got my E/q/q Ult off, I landed the Ult square in his face, and watching it over and over and over in slow mo I see that his Hexdrinker cooldown went off, but it Completely Negated my Ult dmg as Eve ? their was no Loss of hp, no showing that it went off other then in the video it says it's magical energy has been sated, he doesn't have Tank masterie/runes, and based off the Massive damage I was putting on him, I call bullshit that Hextech alone was enough to Negate the ENtirety of Hextechs shield with no animation, and No hp loss, if anything he seemed to Gain a little Hp.
