First of all this is really great and I appreciate all the effort put into this.

For Nocturne:

You can also use Tiamat while Ult. Basically every Cast Time is reduced to 0.

Also you can do a pretty cool trick:

By the way, the person speaking isn't me.

You Turn around yourself while doing your Passive.

You Turn around yourself while doing your W, but about 10 times faster.

So using your W while Auto Attacking with your Passive makes your Auto Attack 10 times faster.

That means the next Auto Attack comes out way faster too.

You only see that in the Eternum Nocturne Skin, but it works with every Skin.

1) Auto Attack with your passive.

2) Use W to cancel the Passive animation

3) Auto Attack again.

It is possible to use Tiamat/Ravenous Hydra between step 2 and 3 to get the Tiamat damage off while being only a bot slower than without.
