Ellen's signature weapon Deep Sea Visitor continues to be her best in slot for Ellen's build however other S-Rank options such as Myriad Eclipse, Heartstring Nocturne and The Brimstone are also great options alongside a range of other viable S-Rank W-Engines. Some good A-Rank build options include Starlight Engine and the event W-Engines.

Build Woodpecker Electro on Ellen for the 4-Piece Drive Disc set while 2-Piece options are Puffer Electro, Astral Voice, Branch and Blade Song as well as Polar Metal. All 4 options are incredibly similar with the best realistically being whatever has more good stat rolls. Astral Voice is slightly better while being a more universal option to farm for many Agents making it the best option if you are just starting to build Ellen for the first time.

With regards to Ellen's substat priority, CRIT Rate > CRIT DMG in the sense that you want to build Ellen as close to 100% Rate as possible without overcapping of course.

How to Play Ellen Joe

Ellen's gameplay revolves around gaining and spending Flash Freeze Charges to deal massive damage.

Ellen can enter the Roaming state when holding/double pressing Dodge or when performing a Quick Assist. While in the Roaming state, Ellen can perform a held Artic Ambush as a Dash Attack. This allows her to deal Ice DMG and gain Flash Freeze Charges.

6.1.

What are Flash Freeze Charges?

Flash Freeze Charges are a mechanic unique to Ellen. They are shown under Ellen's HP and have a max stack of 6. These can be gained and spent in several ways:

Gained Stacks Spent Stacks
Using a Basic Attack while Roaming. +1 Using a Basic Attack while Flash Freeze is in effect regardless of if an enemy is hit. -1
Using a Charged Attack while Roaming. +3 Using Dash Attack outside of Arctic Ambush. -1
Using EX Special Attack Tail Swipe or Sharknami. +1 Using Basic Attack: Glacial Blade Wave. -2

The Flash Freeze state is active whenever Ellen has Charges. This is also indicated by her weapon having an Ice effect.

6.2.

Ellen Joe Combos

Ellen's default combo is the following:

  • Charged Dash Attack
  • Glacial Blade Wave
  • Basic Attack
  • Icy Blade

This both generates and spends 3 Flash Freeze charges because Ellen's Dash Attack can chain directly into Glacial Blade Wave. Ellen's Dash Attack requires you to be in the Roaming state which can either be entered manually, through a Perfect Dodge or through a Quick Assist. This combo can also be extended on further using Ellen's EX Special: Tailswipe into another Basic and Icy Blade for as long as you have energy. That being said the animation for Icy Blade is long as you should swap to other Agents.

Ellen's stun combo is a little more complicated however and does want you to manually cancel your chain attack to go into an EX Tailswipe and EX Sharknami at the beginning of the stun.

Ellen Joe Team Comps and Synergy

DPS Stun Support Bangboo
Ellen Joe Lighter Astra Yao Snap
Ellen Joe Von Lycaon Astra Yao Snap
Ellen Joe Soukaku Sharkboo

Ellen's best team currently involves Lighter and Astra Yao. That being said there are other great Stun options, the main one being Von Lycaon however any Stun can do the job. The best alternative to Astra is Soukaku due to the powerful buffs she brings however Lucy and Alexandrina Sebastiane are also decent.
