Step 1: Push Data Bank to Level 21 for 100% Golden 5-Star Drops
Fill out your Echo Gallery by defeating every creature variant across Solaris-3. Reaching Data Bank Level 21 permanently raises your 5-star golden Echo drop rate to 100% and unlocks cost 43311 equipment setups.
Step 2: Leverage the Alternating Overlord Boss Pity Rule
Calamity and Overlord 4-cost bosses operate on a 2-kill pity counter: if a boss does not drop an Echo on kill #1, kill #2 of the same boss is guaranteed to drop an Echo. Rotate between Bell-Borne and Crownless to maximize efficiency.
Step 3: Prioritize Crit Rate / Crit DMG Main Stats on 4-Cost Echoes
4-cost Echoes offer powerful Crit Rate (+22%) or Crit DMG (+44%) main attributes. Never invest high-tier Tuners into flat HP or DEF 4-cost pieces for main DPS resonators like Jiyan, Yinlin, or Changli.
