Izanami Conquest and Joust build (60% win rate)

DB instead of Malice? Also, getting a high power item ( Transcendence) and then going for more power instead of attack speed feels redundant.

Sorry Bran, but this is not true.

On Izanami it's better to build Malice+unicorn cause of her scalings and her being close to a mage.

No, Asi is not okay. The only lifesteal item you should build on her is Soul Eater, and i dont even build it.

Dont build exe on her because of her passive. Build Titan's.

Malice is better than Deathbringer most of the time on Izanami, due to the fact that Malice doesn't care if your hits deal 50% less damage, while DB does.

Let's say that X is your physical power, and that Izanami is at level 20.
A Deathbringer crit will deal (77 + 0.5X) x 2.4 damage, or 184.8 + 1.2X.
A Malice crit will deal (77 + 0.5X) x 2 + .75X damage, or 154 + 1.75X.

Malice crits exceed Deathbringer crits in damage at 57 power. If you're only fighting with your steroid up, however, Deathbringer is the better choice. Crit in general is less effective on Izanami (except against clustered groups of enemies, but that's only common for minions), since they're only going to deal 50% of their normal damage.

Overall, I would replace Rage for Qin's Sais/ Deathbringer, add Ichaival, and switch in the items that GGF said to. I'd still initially keep Warrior Tabi, though. You have high scaling, no power (at that point) to take advantage of it, and a strong AS buff already. Only after the rest of the build is finished would I sell it and buy Ninja Tabi. Your build order should look something like:

Death's Toll.
Warrior Tabi.
Ichaival.
Soul Eater.
Qin's Sais/Wind Demon. I'm personally a fan of always having WD as my first crit item, given how it smooths out the crit item curve.
Titan's Bane.
Sell DT for Wind Demon/Malice/Deathbringer. If you got Qin's Sais last time, go for WD. If you got WD, go for Malice/DB.
Sell Ichaival for Malice/Deathbringer.
Sell Warrior Tabi for Ninja Tabi.
MAYBE sell Soul Eater for Bloodforge. Stacking gets tedious as the game goes on, BF's passive doesn't count against Izanami's passive, and it also provides a large 75 power. It's very expensive, though, so I would only get this when you really don't need anything else.

Sorry if I went too far with the changes! I do that a lot. The new build plays mostly the same (it needs a bit of stacking now), but it should remove the inefficient items and improve the power curve.

Let me add on by saying that a win ratio does not prove a build to be valid enough to be used all the time, that should be cut off from the title.

In her cons you say she has no good penetration, when that is item based and she has a passive..? That should also be cut off.

3 crits I would only do with Izanami, but one of them still has to be Deathbringer to bring the most burst and dps. I would not get The Executioner for Izanami just for the fact that she already has pen in her passive and her basics dont proc on every god hit, only on the first one hit. Titan's Bane would be a good choice since it does not need to proc.

If you still want three crit items (I dont blame you) switch out Warrior Tabi for Ninja Tabi and look for Soul Eater as an alternative to Asi. Soul Eater allows you to survive with your passive still online, while Asi will make you go above the threshold.
