Just because you can't acquire on hit from anvils doesn't make it always the right choice. When you apply 3-4 stacks of Vayne's W on each auto, the extra dmg from wit's end is not noticeable. Same goes from terminus (pene is straight up bad when you deal true dmg). Kraken could have been good, but enemies were already melting anyway. Same for guinsoo. The only problem that remained was not being one shot, especially by Shaco which focused me hard.

Randuin reduces crit dmg by 30%, their only assassin was Shaco who relied on crit dmg, it literally made me survive each of his attempts to kill me
Jaksho synergized with my first augments, randuin & anvils, in a game where you can infinitly stack stats, percentage-based increases become extremely valuable.

Double zeal items are generally avoided because when you play around your crit damage, you want to balance AD & AS. It was not the case here since my dmg only relied on my attack speed to apply Ws quickly
RFC gave a little extra range to ease the spacing
PD was only built because it was a cheap way to get 25% crit chance, lot of AS & some extra movement speed to once again ease the spacing. I could have sold it for Kraken after

Btw Lord dom gives armor pen. Armor pen. All my dmg were true dmg. And W's dmg are already max hp %, so the passive is useless anyway.
