## Pull for the new characters

Patch 1.4 brings two new featured operators with distinct functions:

- **Arcane** debuts as a dual-form unit. Her intellect form acts as a nature DPS, specializing in damage output against multiple unit types. Her will form offers more supportive abilities, potentially shielding allies or boosting their sustainability.
- **Lin Ao**—now officially named—fills the electric support role, providing a team-wide attack boost plus healing. Her buffs are especially impactful for squads built around synergy and sustained combat.

Both new characters are useful in adapting to the patch's event modes, map hazards and environment changes.

## Watch for the future operator tease

Several new playable units and a surprise crossover were previewed:

- **Sweet Proxy** returns, with unique mechanics and storyline impact.
- **Kuranta man**—a mysterious future operator noted for visual design and possible new archetype.
- **Typhon**, known from the original Arknights, is confirmed for future release in **Endfield**.
- **[Perlica](/guides/arknights-endfield-perlica-guide)** receives a crossover treatment, appearing as a playable outfit in Fortnite. The release is scheduled for August 14, adding cosmetic and promotional value across the games.

![Announcement screen showing Perlica coming to Fortnite, with a release date of August 14 and character outfit available, featuring Perlica's illustration.](https://api.guides-factory.com/media/seo/og/08-future-tease.jpg "This is the on-screen announcement of Perlica's crossover with Fortnite.")

## Also worth knowing
<div class="tipbox alt"><span class="tag">Worth checking</span>

- **Echoes of War stages do not require separate teams.** Each difficulty stage can be played with any lineup, and you can reuse the same squad between stages without restrictions. This makes full clears much more accessible.
- **Redeem code for cosmetics.** Use the code ENDFIELDRENEW to obtain the Safety Helmet Sticker (cosmetic item).
- **Cross-game collaboration is a notable highlight.** The **Perlica**-to-Fortnite announcement is singled out as a surprise feature in viewer feedback.

## FAQ

### How many teams do you need for Echoes of War?

You do not need separate teams for each stage. Commenters noted that each stage can be challenged with any lineup without affecting the others, so the same squad can be reused across stages. Clearing the lowest difficulty is enough to get all aura barrels.

### What is the best reward to look for in the 1.4 login and event updates?

The patch adds a free name change every 6 months, a birthday feature, and a daily scratch-off event with aura barrels. Echoes of War also lets you earn all aura barrels from the lowest difficulty, so the main value is not locked behind full clears. Talusites can be exchanged for items such as custom emotes and stickers.

### Can you skip Valley 4 and still keep progress?

Yes. You can skip Valley 4 and go straight to Wuling while keeping Valley 4 progress intact. That means you can return later without losing what you already completed.
