At rank 5 with Trinity Force, Vayne's Q has a 1.8s cooldown, so she would be able to proc spellblade almost as soon as it comes of CD. It could be built as a 4th item probably, but it's pretty much not used on Vayne.
Any thought on why Triforce is not good on 
and isn't used by pretty much anyone?
weeaboomer1 votesThat thing is super expensive. Maybe as a 6th item it wouldn't be so bad, pair it with an ER and her Q is 1.2 seconds. Pretty fun imo pressing Q so much during ult with a spell blade.
Just build standard adc and if you got the gold and room, finish it up with a triforce.
Ruin Lance1 votesi get it on her a lot, but you shouldn't get it if you're behind since it's so expensive
Tyrone Lannister1 votesThere's simply better items that are cheaper and give better stats. Tri force is one of if not the most expensive items in the game. If you're gonna put that much investment into an item, you better be able to utilize it to its full potential. Tri force is great on corki and even ez because they rely on their abilities to to the brunt of their dmg. Vayne relies mostly on her autos and her spells compliment the autos. Catch my drift?
Guy Fox Teemo1 votesits INSANELY good if your ahead, but its incredibly expensive, so opting for it usually isn't the best choice, at it takes to long to reach the power spike.
Dunkrius2g1 votesHer base ad is really low for her to properly utilize Triforce. 3.8k can be spent elsewhere.
