Progression

  • Pets level up through their own material track, earned primarily via daily Pet Chests and the Forest of Life zone in Mystic Trial
  • Pet growth generally provides passive stat or resource bonuses rather than direct combat skills — check your in-game Pet screen for the exact current bonus list, since these are patched periodically

Sources

  • Pet Chests — available daily, a steady free source of pet materials
  • Mystic Trial (Forest of Life zone) — one of the best concentrated sources of pet-related materials when that zone is active

Strategy

  • Treat Pet Chests as a "claim every day, don't think too hard about it" system — the daily habit matters more than any single decision
  • Prioritize Forest of Life weeks in Mystic Trial if your pet progress has stalled
