Upgrade Priority Guide
▍Skill Leveling Order
Skill > Talent > Ultimate > Basic ATK
Rationale: Maximize skill’s core DMG output first. Talent improves survivability/energy rotation. Delay ultimate upgrades due to high energy costs.
▍Farming Strategies
Quantum Materials: Daily cap reset for Palace of Forgetfulness store exchanges.
Light Cone Materials: Exchange purple-tier items via Black Tide Workshop event store. Farm memory materials in co-op dungeon Doomsday Phantom.
▍Stat Optimization
CRIT Rate: Minimum 70% baseline (synergizes with Elegies of Dark Night 4pc). Use CRIT Rate chestpiece if substats fall short.
HP: Aim for 28,000+ base HP (0 constellations). Reduce to 25,000+ for high-constellation builds to prioritize offensive stats.
