HO HO HO How are you guys, its me Captain Scy again. First and foremost, let me greet you a happy holiday / Merry Christmas and a Happy New Year 
in advance. Back to the topic, in this guide we will talk about the Gameplay of Vermillion Knight Eclipse ( VKE ) in ER. VKE has two gameplays in ER but for now I will talk about the Ultimate Base Build first rather than Charge Attack Build, But Why? Its simply because this gameplay is safer than charge attack build specifically the invulnerable attack animation such as Ultimate Attacks and Weapon attack, since her kit this time takes alot of Health so that's very important. So that's the fatal flaw of Charge attack build specially if you're not adept in dodging. Anyways, I'll keep the guide simple as possible. I'm a minimalist so sorry ahahaha.
.
Take Note: This guide is created in Beta so minor changes in official is possible. Also this gameplay needs a Signature Weapon - Shuhadaku of Uriel / Might of An-Utu Pri-arm.
PS: I want to try this gameplay using F2P Weapons like Labor of Olympus and the Coop Weapon, sadly the account I'm using only have Gacha gears, they're not unlockable.
As for the Valk Supports and items:
Valkyrie Chariot + Azure Empyrea = Gather Support
Azure Empyrea + Lightning Empress = Sustain SP
Azure Empyrea + Blood Rose = Extra TDM
Items / General + Flame Chaser Support
Crystal Rose + Out of Reach(Kosma) - Early Stages (Until you get the Extra 2 Ego Signets)
Mad King's Mask(Kalpas) + Out of Reach = Early to Mid Stages
Burden + Out of Reach = Mid to End Game
Yeah I think this are the important item and supports, you can also use Veil of Tears (Aponia) and Dreamful Gold(Eden Support). It all depends on what you need.
Signet of Ego 
This is the sequence of Exclusive Signet of VKE for Ultimate Base Build
Fiery Mind(1st Floor) > Burning Flow > Wild Flare
the other two are not needed or optional that will depends on you.
Blessing of Fiery Mind (Recommended) - Each hit of Ultimate deals an additional Fire Damage, decrease Current health (HP > 18%) but heals when HP is below 18%. Also spams 1st Ulti Sequence which auto connects to 2nd sequence on the 4th stack.
- The main damager of this gameplay.
Blessing of Burning Flow (Recommended)- Evasion connects to Guren Flash( The Counter Attack of VKE after Ultimate Evasion). + 20SP and +1 Stack of Ultimate.
-The CDR of VKE Ultimate and Sp regen. It also gives TDM upon triggering Ultimate evasion. But No need Ultimate Eva for the Guren Flash and thats the most important for this signet. Highly Suggested to get this on 2nd floor.
Blessing of Wild Flare (Recommended / Optional )- Losing HP or Casting Charge attack inflict debuff to the enemies to received an additional Fire Damage. Also cooldowns the Weapon Activation Skill.
-Highly Recommended when you have Shuhadaku of Uriel / Might of An-Utu.
Blessing of Blaze (Not needed / Optional) - Faster Charge attack + Charge Damage. Also lessen the heat produce.
Blessing of Sharp Flames (Not needed / Optional) - Charge Attacks deals extra Fire Damage. Pulls/gather surrounding enemies with a 3sec cooldown.
Now lets talk about the General Signets.
My recommended signets are simply straight forward, so it can be easily copy. Here's the sequence
Decimation / Kalpas (2nd) > Deliverer / Kevin (1st) > Reverie / Pardofelis (1st).
These are the main signets I recommend personally for VKE.
Signet of Decimation
*Blade, Grave, and Scar - TDM for every 100 HP Lost.
*Bone, Blood, and Ribbon - Physical and Elemental Dmg for every 100 HP Lost.
*Path, Misfortune, and Written Fate - Increase Max HP.
*Desireless, Mindless, and Homeless - Enemies takes extra TDM if Current HP got reduce.
*God, Me, and the Only - Restores SP for a certain amount of Current HP loss.
Soldiers, Scissors, Spoils and Slaughter(2nd Nexus Core) - Current HP will only regen at 18% of max HP, and Increase Max HP for the amount Valk Healed.
Homeland and Friends(Enhance) - +25% Physical and Elemental Breach when core hits 1500/+ charge and increase Nexus core charge.
Body, Bones, Heart and Soul(Enhance) - when charge reach 1500/+, next attack deals extra adaptive damage after heal. Also increases charge of Nexus Core.
Death, Life, Oblivion and Existence(Enhance - Optional) - after hitting 1500/+, Nexus Core can absorb damage 1% of its charge. Also increases Nexus Core charge.
"Our Main signet" and highly recommended to get the core as soon as possible since VKE's ultimate reduces HP every cast until 18% and below. The regen of HP is also superb that can easily maximize the Nexus Core. This might be redundant but I want to emphasize that. Feel free to upgrade the enhance on the last part of the run since we're going to combine this with Reverie Signet.
Signet of Deliverer 
*Goblet of the Giver(Normal)- Increase TDM% upon using Ultimate for 5sec.
*Brand of the Undead(Normal) - Increase Elemental Dmg upon using Ultimate for 5 sec.
*Artifact of the Inhibitor(Normal) - Increase Elemental Breach upon using Ultimate for 5 sec.
*Rochet of Pilgrim(Normal) - SP Regen upon using Ultimate for 5 sec.
*Blade of the Deliverer(Nexus Core - 1st Core) - gives Final Battle Status, which increase all NORMAL SIGNET by 50% for 5 sec. (E.g: Goblet Giver has 50% TDM + (Goblet Giver 50%TDM x 50%) = 75% Total TDM when Blade of Deliverer is active)
*Crusade of the Deliverer(Enchance)- Increase Nexus Core to 90%/ 108%/ 126%/ 144% instead of 50%.
*Echo of the Deliverer - Extends the Duration of Nexus Core to 8sec/ 9sec/ 10sec/ 11sec instead of 5sec.
*Flock of the Deliverer - Final Battle Status is also considered as Burst Mode. TDM increase in Burst Mode.
(Take Note: if Burst Mode is needed you can considered using this, just make sure not to use this when enemies has a TDR buff when Valk is in Burst mode.)
Reason why not 2nd Nexus Core(Shadow of the Deliverer):
1.Takes too long to maximize the Nexus core and enhances.
This is the 2nd Valuable signet in this gameplay since we'll be spamming ultimate here, but it doesn't necessary mean that you should get this on the early part.
Signet of Reverie 
*Shiny and Valuable - Extra coins for every enemy kills
*Neighborhood Chatters (Highly Recommended)- Additional HP and SP for every 100 Coins
*Back Curled Tail - Additional Physical and Elemental Damage for every 100 Coins
*Motto of Meow - Additional TDM for every 100 coins
*Merchant Philosophy - Extra coins after finishing the floor that ratio on your current coins
Empty Dreams, Self, Set, and Joy ( 1st Nexus Core) - additional Physical and Elemental damage 500/1000 coins.
*This Is Not Were We Die(Enhance)(Optional) - Damage Blocker + Physical and Elemental Breach.
I personally recommend this signet for VKE, this signet can double - triple the effect of Kalpas' Normal signet. Hitting 18-20k is an easy feat with this signet. That means an estimated 100%-190% additional Kalpas buffs we will be added on the end part.
Finally, lets talk about the Optional Signets if portals get dicey since they really do time to time, here's a list of them:
Signet of Discipline / Aponia (2nd Core) 
- You Shall Receive Disciplines' Blessing - VKE can easily lowered the stack of this signet so you need the 2nd Core. Fourth, No Insolence > Fifth, No Falsehood > Sixth, No Decadence, these three are what you prioritize when getting the core.
Signet of Gold / Eden(2nd Core) 
- Echo of Gold - We will be using alot of SP here obviously, also its a good optional because of Pardofelis Signet as I mentioned on my earlier guides.
Signet of Daybreak / Kosma(2nd Core) 
- Daybreak, Lone Beacon - Optimal TDM, Elem Breach, Elemental Dmg, and Adaptive Dmg are good in this signet, the downside is this Core also decrease you current health depending on the stack of the "Rend". So be careful using this Nexus Core.
Signet of Helix / Vill V (2nd Core) 
- Intermezzo: Holistic Helix - Simply Maximizing the weapon Uriel. and also the gather effect. Ahahah
Here's a Sample Full Run for VKE Gameplay on ER.
Final Thoughts:
I was excited when I heard VKE joining ER so I created the tutorial first before the promise valk I mention in the past guides. Things didn't go as planned since its a busy season and didn't get the Valk in the gacha ahaha. Also its the debut of one of the most important person and Batttlesuit in Honkai so I will definitely do this first. So I feel that its right thing to do something like this as a legacy of her.
Anyways, hope you get something in this Guide and made your gameplay easier and fun once you tried VKE in ER. Also the VKE in the Video is SS Rank, its already SS when I open the account so I cant try it at S0 Rank. If you have any Questions and Suggestions, feel free to comment below.
