Watch for enemy waves, that nagging Ether Corruption DoT, and resets every other Friday.

Quick Dive into Shiyu Defense's Ambush Node & the Ethereal Twins

Shiyu Defense 101 in ZZZ

This mode drops five stages across Sep 25-Nov 6. S-Rank nets you 600 Polychromes. Drop to Rank 1? Still 30 Polychromes plus 20,000 Denny. Rank 2 gives 30 Polychromes, 15,000 Denny, and 5 Noise Reduction Master Copies. Stable Node pays 3,000 Polychromes; Disputed 1,600; Critical 720; Ambush 600. Chase S-Rank every time—over 300 seconds on the timer, no defeats.

How the Ambush Node Actually Works

Five Frontiers, two teams per stage. Frontier 1: Team 1 weak to Fire, Team 2 to Ice/Physical (but resists Fire). Frontier 2 flips it—Team 1 Electric (Fire resist), Team 2 Fire (Electric resist). Frontier 3: Team 1 Ice/Ether, Team 2 Electric (Fire resist). Frontier 4: Team 1 Ice/Ether, Team 2 Physical (Ice resist). Frontier 5: Both teams Fire/Physical, with Team 1 weak to Ether/Ice and Team 2 to Ice. Global buffs? Agent ATK +30%, CRIT DMG +15%, Stun DMG +20%. Pro moves: Match weaknesses spot-on, hold Ultimates for the last waves, cluster up for EX specials.

Meet the Ethereal Twins (New Season Shake-Up)

These bosses crumble to Ice and Ether. First half waves: Wave 1 brings 3 Vicious Strikers; Wave 2 a lone Frenzied Maniac; Wave 3 mixes 2 Vicious Strikers and 2 Greedy Rangers; Wave 4 unleashes 1 Wicked Wraith (Fire-heavy). Second half: Wave 1 has 2 Ionized Cyrtoidea plus 2 Ionized Nassellaria; Wave 2 one Ionized Farbauti; Wave 3 caps with 1 Ionized Dullahan (Ether EX special).

Breaking Down the Ethereal Twins Fight: Phases and Tricks

Phase 1: Dodging Attacks and I-Frames

Ether Corruption DoT loves to interrupt—build for Anomaly Mastery (Proficiency ramps it up). Slot Vivian as sub-DPS for her EX. Key plays: Position for bursts, slap on Ice/Ether right away, parry those charges.

Phase 2: Handling Dual Attacks and Synergy

Take out both Twins at once to stop resurrections. Herd those Ionized Ether waves together. Burst in the synergy windows; chain T0 Dialyn Stuns for killer buffs (they outshine others); lean on Astra Yao's Ultimate for heals and CRIT DMG spikes.

Weaknesses and Resistances at a Glance

Ice/Ether owns Frontiers 3-5. Fire hits Frontier 1 Team 1 and 2 Team 2; Electric shreds 2 Team 1 and 3 Team 2; Physical for 4 Team 1 and 5 both. Resists? Fire on 1 Team 2 and 2 Team 1; Electric on 2 Team 2; Ice on 4-5 Team 2. Swap teams like clockwork.

Meta Pick #1: Freeze Comp That Locks 'Em Down

Lineup and Roles

For Frontier 3/4 Team 1: Ellen and Zhu Yuan as Ice/Ether DPS leads, back 'em with Astra Yao, Caesar King, or Nicole Demara for Stun/Support. Ellen freezes the field; Zhu Yuan piles on Ether Corruption. Subs like T0 Vivian or Yixuan shine here.

Meta Pick #2: Electric Anomaly Shredder

Team Lowdown

Frontier 2 Team 1: Tsukishiro Yanagi, Vivian, Trigger, Caesar King (Electric DPS core), with Astra Yao, Ukinami Yuzuha, or Alexandrina on Stun/Support. Ether swap: Astra/Yanagi/Vivian/Robin. Trigger's off-field Daze and buffs are clutch.
