I just have a technical question about the item.
Say on an ad champ you buy this 
, will the passive effect of this item cancel out any AD damage your autos would originally deal, or is it a combination of your AD + the on hit (+15% of ap)? (For example if you built it on someone like Yi)
Shadòw3 votesAD + On hit.
Deep Terror Nami2 votesThe Nashor's damage is a bonus on top of your normal damage, what you currently do isn't converted (the way Corki does). Basically, don't buy it if you are not stacking AP and also need attack speed. This is usually limited to something like Azir, Teemo, or Kayle.
HoloFate1 votesInteresting, let's say you were stacking the AP, would you say something like wits end is possibly a better item for the job?

AP Champion that scales well with attack speed (like Teemo): Nashor.
AD Champion that scales well with attack speed (like Shyvana or Vi): Wit's End.
Although it really isn't a core item; only something I would get if the enemy has lot of Magic damage. I'd probably get 
over it in most cases.
Deep Terror Nami1 votesNashor's Tooth is already very much a niche item, and Wit's End is even worse. If you need the MR stats from it you're better off splitting your purchases into multiple items with what you need. I think AP Warwick can use Wit's End effectively, but I don't think I've seen a WW on the Rift in a year and a half.

Hopefully that will change come January/March.

Feedlife Ezreal1 votesI've had some reasonable success using it on AP Ezreal, but the majority of the games don't really last long enough for me to build it. Something like:
But alot of the games I've had, by the time I finish gunblade/arch staff/boots/lich bane the game is closer to over. Anyway it's interesting, but void staff might be better depending on the game.
