Zenless Zone Zero Yidhari Dream Event Guide: Rewards, Tips, and Ridu Chronicles Access

I still remember the first time I entered Yidhari's dream through the Echo Chamber in Failume Heights. As a professional player, I have cleared a lot of limited-time content in Zenless Zone Zero, but this dream investigation stood out because it paired an emotional memory storyline with a surprisingly tactical turn-based companion duel system. The original event ran from October 17, 2025 at 10:00 server time until November 24, 2025 at 03:59 server time. Now that we are in 2026, the full content is preserved in Ridu Chronicles, so Proxies can still explore the dream, battle with monster companions, and experience the narrative. The key difference is that limited-time mission rewards are no longer claimable after the event window, so my advice is to treat the Ridu Chronicles version as story and gameplay cleanup rather than a reward farm.

Before you dive in, make sure your account meets the entry conditions. You need to reach Inter-Knot Level 15 and complete the Agent Story "Mole in the Hole (I)". Once the event begins or appears in Ridu Chronicles, head to Echo Chamber in Failume Heights and find Lucia and Manato. They serve as your entry point into Yidhari's lost memories. During the original run, new Dream areas were unlocked over time for Dream Investigation, which kept the event feeling fresh. If you are playing through Ridu Chronicles now, I recommend pacing yourself through the full sequence to appreciate how each recovered memory expands the emotional core.

The event gameplay is the real highlight for me. You can command up to four allied monster companions in a duel. Each side takes turns using skills in a set order. This is not a mindless auto-battler; timing matters a lot. During the opponent's turn, you can use Instant Interactions at the right moment to dodge enemy attacks or enhance allied skills. If you master the timing windows, even a weaker monster lineup can clear difficult duels. Winning duels lets you collect new monsters as companions, which adds a collection loop that encourages replaying stages.

Here is a quick breakdown of the core systems I focused on:

• Monster Companions: Up to four allies can be commanded in each duel.

• Turn Order: Both sides act in a fixed skill sequence, so you can plan around enemy patterns.

• Instant Interactions: Use precise timing during enemy turns to dodge or buff allied skills.

• Dream Investigation: New Dream areas unlock progressively during the event period.

• Collection: Win duels to recruit new monster companions and expand your options.

The recommended preparation is important. The game advises completing Main Story Season 2 Chapter 4 "Memories of Dreams Bygone" before participating. I agree with that recommendation. The event story references dream logic, memory loss, and Yidhari's past, so having the main story context makes the emotional moments hit much harder. If you skip the main story, you can still follow the basics, but you may miss why certain scenes matter.

Rewards were a major reason to clear the limited-time missions. I always tell other Proxies to prioritize these before an event expires. The event offered Agent Komano Manato as a playable reward, a Hamster Cage Pass, Polychromes, and various upgrade materials. These are valuable for account progression, especially the Agent unlock and Hamster Cage Pass. If you are playing after the event window, do not expect these limited rewards to be delivered. The game clearly states that limited-time rewards cannot be claimed after the event is over.

From a professional player perspective, I recommend building a consistent duel strategy rather than randomly pressing instant interactions. Watch the enemy turn indicators, memorize the fixed skill order, and save your Instant Interaction for the most dangerous attacks. If you can dodge a key enemy skill, you will preserve your monster companions and close out fights faster. When you win, check which new monsters you collected and try different team combinations. Some companions work better against specific enemy patterns, so experimentation pays off.

Another tip is to complete the main story prerequisite first. Even though the event only requires Inter-Knot Level 15 and Agent Story "Mole in the Hole (I)", finishing Season 2 Chapter 4 "Memories of Dreams Bygone" gave me important context for Yidhari's dream and made the event feel like a proper epilogue. If you are short on time, focus on the limited-time missions first, then return to story cleanup later.

In 2026, I still consider this dream investigation a must-play piece of Zenless Zone Zero side content. The dreamscape presentation, monster duel mechanics, and emotional memory story all work together. The permanent availability through Ridu Chronicles is a huge plus because it lets new Proxies experience the full event at their own pace. Just remember that the original limited reward window has ended. Plan accordingly, manage your resources, and enjoy the journey through Yidhari's lost memories.
