Zenless Zone Zero (ZZZ) Shiyu Defense Guide and Overview for Critical Nodes

The Critical Node is comprised of stages that rotate on a twice monthly basis. Critical Node stages focus on killing enemies within a certain amount of time, and meeting certain thresholds will grant you the maximum rewards. You will be able to gain up to 720 Polychrome from this content, provided you manage to clear all five stages on S-Rank. Each stage has 3 sets of rewards that you can gain at B, A and S-Grades respectively.

Clearing any stage at any grade will unlock the next one for you, so don't fret if you do not manage to get an S-Grade immediately. Depending on how many stages you have cleared in the previous cycle, you may be able to skip some stages. S-ranking all 5 Critical Node stages will allow you to skip the first 3 stages in the upcoming cycle.

In this guide we will provide detailed information on each of the 5 stages, highlighting the weaknesses of the enemies in each stage, as well as potential team recommendations that might make your life a little easier in order to claim the mode's rewards.

Keep in mind that a well built character may perform better than others, even if it does not match the enemies weakness. Just make sure to not pit them against enemies that are resistant to their damage type.

There are 5 stages in the Critical Node section of the Shiyu Defense. Each stage has its own set of enemies, buffs and effects that boost your characters, as well as their own Challenge Target time-limits. In each stage you will have to field 2 teams, requiring 6 Agents and 2 Bangboos total. You cannot use the same Agent or Bangboo twice. The final stage requires 3 teams instead.

Disclaimer: Depending on your account, you may only have a handful of characters leveled and equipped. While this guide will recommend different teams for different stages, you are more likely to succeed by playing your highest level characters that you have the most practice with, instead of the ones that match the stage's bonuses and vulnerabilities. Simply make sure to not field a team that the enemy units have resistances against, and try to take advantage of the bonuses granted each cycle.

Use the Stage-Slider to select the stage you would like more information on.

The first 4 nodes of this rotation of Critical Nodes heavily emphasize triple Anomaly DPS. Because of this Remielle Dan is ideal for these nodes as she takes full advantage of the triple Anomaly niche. However traditional Anomaly teams will also clear content just fine as the buff specifies two or three Anomaly Agents so teams with Ukinami Yuzuha will perform well.

The final node includes fights with the following bonuses:

• Room 1: If there are 2/3 Agents with the Anomaly specialty in the squad, Attribute Anoamly DMG dealt by the Agents increases by 10%/60%, and the whole squad initially gains 500/1500 Decibels upon entering Combat.
• Room 2: Agent's Ultimate and Chain Attack DMG increase by 40%. When a Chain Attack hits an enemy, the enemy's Stun DMG Multiplier increases by 20% and Daze recovery speed slows down by 15% for 15s.
• Room 3: Agent Ice DMG and Electric DMG increase by 30%. After an Agent with the Attack specialty uses an Ex Special Attack, their CRIT DMG increases by 30% for 20s.
