Tips for Efficient Item Farming

• Prioritise prerequisite lore: Upgrading Memories, Secrets, and other lore early unlocks higher‑tier actions sooner.
• Watch item timers: Anything marked 24 h or 48 h expires in‑game—use or process it before it spoils.
• Combine actions: Many consumables feed directly into Boon recipes; plan rooms in loops to save travel time.
• Log your finds: Keep a quick spreadsheet or note app with room + favourite action to avoid back‑tracking.
