I've heard people say it doesn't but everytime I see a nasus play or even when I play him even though I have only trinity force and the rest tank some how I end up beating and out criting adc's or someone like trynd or yi when clearly theyre whole kit is crit if it doesn't then is the big red damage text for crit is false?
Only Play Darius2 votesIt used to. Not anymore.
If it crits it only doubles his base AD, not his stacks. Yes, critting used to double the damage from stacks. 
was back then as essential on him as 
lmfao.
PedramCarter1 votesI think it still does if you ever play a good nasus or just normal nasus you will notice he has the largest crit (providing he build trinity)
redniwediS1 votesFull AP Anivia gets really large crits too. The end game numbers are a little wonkey like that. All I can tell you is that the in game calculations are correct, with Nasus not getting stack crits.

His stacks don't crit, but they are a part of the autoattack, so your stacks will be included in the number. Thus, a Nasus building no AD can still get the highest crit
Oddysseas1 votesI believe it does
IcyPepper1 votesOh god no, I hope. The guy can melt towers as a full tank already.
Oddysseas1 votesYou can make a custom game, play nasus build crit and test i, just saying...
Kingsgrave1 votesIt crits additively but it doesn't factor in the base damage.
TyWdtSHg1K1 voteshell yeah it crits dude
Sire Hippington1 votesThe AA does crit, but the bonusdamage from Q is added after the crit multiplication. For example, you got 150 ad and Q adds 400 damage. A normal Q hit would be 150+400=550damage, a Q crit would be 150X2+400 = 700 damage. All AA-modifiers work that way unless they explicitly state that they can crit in the tooltip.
