Vivian (S Rank)

• Rating - ★★★★ (Very Good)
• Effect
  • When Sunna enters the battlefield, she gains 15 Energy. In Investigation Zone Mode, this effect can trigger once every 180s.
  • When Cat's Gaze triggers and hits an enemy, the target's DEF is reduced by 7% for 40s, stacking up to 3 times. The duration of each stack is calculated separately.
• Reason - Adds Energy on entry and introduces a stacking DEF reduction tied to Cat’s Gaze. This improves team damage output and scales well in longer fights, making it Sunna’s most valuable early Mindscape.

• Rating - ★★★★★ (Amazing)
• Effect - While Sunna is within any Ether Veil, all squad members gain 10% ATK and she gains 1 Claw Sharpener every 10s. Cat’s Gaze requires fewer hits to trigger, and its DMG Multiplier is increased by 200% when triggered by Attack characters and 300% when triggered by Anomaly characters.
• Reason - This Mindscape significantly strengthens Sunna’s core mechanics. It boosts team ATK, improves Cat’s Gaze reliability, and massively increases Cat’s Gaze damage, especially in Anomaly teams.

• Rating - ★ (Low)
• Effect - Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
• Reason - Skill level increase only.

• Rating - ★★★★ (Very Good)
• Effect - When Sunna uses her Ultimate, all squad members deal 18% increased DMG for 60s.
• Reason - Provides a long-duration, teamwide damage buff.

• Rating - ★ (Low)
• Effect - Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
• Reason - Meh. Same reason as M3

• Rating - ★★★★★ (Top-Tier)
• Effect
• • When Sunna uses an EX Special Attack, she enters the Focused Creation! state for 8s.
  • While in the Focused Creation! state, all attacks Sunna performs are guaranteed to CRIT, and her CRIT DMG increases by 0.03% of her initial ATK, up to a maximum of 105%.
  • While in the Focused Creation! state, Sunna's Anti-Interrupt Level is increased, and DMG taken is reduced by 40%.
  • While in the Focused Creation! state, Sunna can trigger Cat's Gaze, its DMG being calculated using Attack Agent rules. If Cat's Gaze is triggered while Sunna has a Claw Sharpener, the Claw Sharpener is immediately consumed, and Cat's Gaze is reapplied to the enemy. 
  • While in the Focused Creation! state, DMG dealt when any squad member triggers Cat's Gaze increases by 50%.
• Reason - This Mindscape dramatically raises Sunna’s ceiling. It turns her into a powerful support–DPS hybrid during Focused Creation!. Massively boosts Cat’s Gaze damage for the entire team, enabling extremely high DPS potential.
