- How to read IVs and appraisalsIVs run from 0 to 15 for each of Attack, Defense and HP, and appraisal stars are set by the sum of the three (0–45).
- What to power up first (power-up priorities for beginners)Stardust is limited, so first power up strong counters you'll use for a long time across many raids.
- Choosing IVs for PvP (low Attack wins in Great and Ultra League)In leagues with a CP cap, the lower the Attack IV, the higher you can level up within the same CP, which makes Defense and HP bigger.
