Guidance
Nangong Yu asks less of you than the other anomaly builds on the roster. His Anomaly Proficiency target of 280 is the lowest of any Proficiency-led agent here, against 173 Anomaly Mastery and 2,200 ATK. Where Vivian needs 380 and Jane 375, he is comfortably short of both. That makes him a good early anomaly project: the thresholds are reachable without a long farm, and the goal component is 20% of the grade. His structure is the familiar one. Slot 4 accepts Anomaly Proficiency only, slot 6 Anomaly Mastery only, slot 5 free across Ether DMG, ATK% or PEN Ratio. Anomaly Proficiency leads his substat weights well ahead of ATK%. Nine loadouts sit across Phaethon's Melody and Freedom Blues, with six accepted partners for the top choice, one of the wider partner lists here. Phaethon's Melody also equips Vivian and Aria. Get the two locked mains right and he reaches a good grade faster than most.
