Empress of Light Daytime Easy Summoner Strategy

Hello everyone.
I made this simple video tutorial/exhibition for a simple, reliable, fast setup to beat the Expert Daytime Empress of Light (but also has tips to beat master).

Whip: I chose durendal to show that it is possible without having to grind for a better whip, but if you happen to have it it will be faster, as shown in the video.
I beat her three times. Two with the durendal to show it is reliable in strategy and timing, and third with the dark harvest, to show how quicker it is with it.
Summon: The ufo summon is so good it was hard to exclude. It is pretty doable even with sanguine staff but it will take a little bit more and it could make a huge difference. The purpose of the video is to have a 100% simple and reliable strategy with little to no excecution, and sanguine staff doesn't quite reach that criteria.
Mount: the witch mount gives you indefinite flight and just enough speed to escape almost every attack (see 1:24).
Buffs: well fed, venom flask. + Optional Night owl for video clarity.

The strategy is pretty simple: in the first phase it is pretty easy to learn the patterns and dodge indefinetely, but here that is not gonna be a problem since we DON'T WANT her to do even half of the second cycle. That is the indicator that we have enough damage to be able to power through the second phase with relative ease.
In the first phase, we just need mostly left and right motion to dodge everything. The key is to be already in motion while the she attacks, never stay still.
Comet attack (0:38): go in one side direction and after she is done releasing comets you go slightly up.
Dash attack (0:41): she always dashes slightly above you, so either you preemtively go up (0:41), or go down (0:50) because you won't make it up. It's always safer to go down, but I advise to go up in some cases to gain height to simplify future dodges.
Light flower attack: you can easily escape it by just running, but stay close to deal important damage. Remember that once a petal turns off it is off for good.
Star circle attack (0:51): RUN. comet attack n.2 is coming!
As you can see in the video, following these steps you have gained enough height to easily dodge the
Spread beam attack (0:59): go straight down until the attack starts and do a quarter circle turn (90 degrees) in either direction.
Now you should go to phase two. This is the moment you want to switch to phase two, if you want enough damage to have it easy.
Phase two is the same as phase one, the two new attacks use the same dodges we already made. The first attack is always the
Multiple beam attack (1:10): use the height you gained and go STRAIGHT DOWN. When the third bunch of beams appear (1:12) take a 90 degree turn (like with the spread beam attack). You might be tempted to go up or down now but don't. Stick with the direction and you will be 100% safe.
Now after the comet attack he will do a direct beam attack (1:20). Do a circle, it's much easier to do than to think. and then stick with the original direction.
Here is the only move you'll have to do: EoL will do a Star circle into comet into flower. This time you can't dodge up, and you can't move down fast enough reliably. So ditch the mount for a second. You'll be far away from both the flower, the stars, and the comets for an easy dodge. Switch the direction right after remounting. This is the only critical point, if you kept doing damage. Now EoL should die. if she still has some hp, you'll have to do one last dodge. If you manage your height well you can go down for the next multiple beam attack, if you don't you can dodge the same way by going up. It looks like it would hit you but don't be scared, if you don't stop, you're safe. (1:36)
And that's it. Lots of words to go left right up and down. You just defeated Empress of Light in expert mode. If you follow the same tips you will be able to defeat her in master mode too.

Have fun with your Terraprisma!
