How does tenacity stack and what are the optimal amounts?

On Tryndamere my hardest matchups are high cc teams, and poke champs like teemo. Normally I get merc treads, but I always forget to change from alacrity to legend tenacity, and I feel like that gimps me. Unflinching might be better than legend tenacity unless you can get both and merc treads, but when does teemo's blind hit the bare minimum of .5 seconds? How much tenacity do I actually need? I'm surprised there isn't a tenacity calc for common abilities. I want the blind to last as little of a time as possible, and nasus wither as well if anyone has the numbers on how much tenacity I need. How does tenacity stack exactly?

They stack. They all stack, but mostly only multiplicatively.

That they stack only multiplicatively for the most part, should tell you, that Riot considers Tenacity to be a broken stat.

Mercs + Sterak's are additive.

Iron + the initial %10/%20 bonus from Unflinching are additive.

Any champion can get %77 Tenacity from mercs, Legend:Tenacity, Elixer of Iron, and fully stacked Unflinching. (This will just begin to scrape the .5s Tenacity hard cap on a 2s CC.)

Without the Unflinching it's still a reliable %63. We haven't bothered to include Sterak's procs, or Cleanse.

That's %63 Tenacity from 3 sources that are pretty easy to have all together by midgame.

(Smite DOES proc Unflinching. You can maintain a fairly consistent (well, on-demand, but easy to get) %32 Tenacity without mercs, just by running Unflinching and Smite.)

The %10/%20 component of Unflinching does stack additively with Elixer of Iron. One advantage of Unflinching is that you have full use of it lvl 1. Legend Tenacity probably takes about 12m to fully stack.

Nasus wither is 5s. (The longest CC in the game.) (You can see your Tenacity stat in game when you look at your full stats with C. When you have mercs, it says %30. Buy Iron, and it goes up to %48. Mercs + Legend = %51.) So you can get Wither down to 2.5s pretty easily and with all three, almost to 1s. If it's only slows that you're worried about, then Slow Resistance is better. If Teemo is your only concern, probably get the Swifties and some other MR.

Unflinching ALSO give %15 Slow Resistance. All Slow Resistance stacks additively.

Teemo blind scales with ability points from 1.5s to 2.5s. It's not the kind of thing that I think about buying Tenacity for. (Swifties would also just help you dodge Teemo darts. Much better not to get hit at all, right?)

If you ever do get CC down to .5s you hardly notice it...

If you REALLY want to max your Tenacity, then you need to bring Cleanse. Then you get %65 Tenacity for 3s on a 3.5m CD. (And if you also took Unflinching, then keep some extra Tenacity for that whole time.) Cleanse stacks multiplicative with the other forms of Tenacity. Stacked with the other three, you would have %87 Tenacity for those three seconds.

CLEANSE - THE RAREST SUMMONER'S SPELL CHOICE (adapted from SpikeThePike)

Cleanse deals with hard CC (and gives 3 seconds of tenacity to help against chained CC). It can be viable against specific opponents with a lot of hard, long duration CC, opponents like Ryze, Veigar, Lux, Zyra, Zoe, Ivern, Irelia, Jax, Elise, Sejuani, Morgana, even Lissandra. It is more powerful than it seems, because when you are hit by hard CC you cannot use Flash but you can still use Cleanse.

It partly depends how skilled (and awake!) you are - if you are good you can probably dodge most skillshots without needing this. But some of these opponents, for example Ryze and Irelia, are undodgeable. It can be used to bait an opponent like Jax or Irelia, as they will not expect you to break from their stun!

Having said all this, you should be buying a Quicksilver Sash in a game like this. This item does the same job as the Cleanse summoner but on a much shorter cooldown so you can use it more. And it builds into Mercurial Scimitar which is a reasonably good 6th item for Tryndamere anyhow. OK, QSS has a gold cost, but maybe one of the other summoner's spells like Flash or Ignite can earn you gold by giving you an early kill...

Tenacity stacks multiplicatively, so that each reduction is an equal ratio.

If you have 10% tenacity and a new source gives another 10%, the second source reduces CC by 10% of 90%, or 9%, for a total of 19% reduction.

the most tenacity you could have by taking legend tenacity and mercs is 51%

Along with what others have already pointed out, there is actually a minimum cc duration of 0.5 seconds that no amount of tenacity can reduce below
