Cube Palace STEP 2: Kernel (Naru & Lugh) Walkthrough

STEP 2 Kernel boss guide: cleansing Naru & Lugh's Freeze/SPD-Down debuffs and playing around Naru's Enhanced Counter stance.
STEP 2 Kernel (Naru & Lugh) Clear Strategy
STEP 2 bosses Naru and Lugh have only single-target attacks, but every hit inflicts Freeze or SPD Down. If Lugh attacks a debuffed target, he fires a follow-up Basic Skill (with 2-turn Freeze!), and hitting Lugh while debuffed boosts his Action Gauge. Meanwhile, Naru gains DMG Up / DMG Reduction per debuff on your team and activates Enhanced Counter on her Special Skill.
Bring 1 Defender (Haydee) to funnel single-target debuffs, pair her with debuff-cleansing Supporters (Asherah: Waltz of Starlight or Frey) plus Cleanse Cheat Codes, and hit side adds or cast non-attack skills while Naru's Enhanced Counter buff is up.
