Note numbers will be updated for global when exact start, end, and maintenance times are known.

• Event Currency drops from any stage outside of Annihilation, Challenge, and Extreme Modes.
• Total needed to clear shop: 1940
• Total from First Clear rewards: 560
• Remaining currency needed: 1380
• Currency drops at a rate of 1:1 for sanity spent, so 1380 Sanity is needed for stage farming
• Sanity required for First clear of Challenge mode: 87
• Total Sanity required to clear the Store: 1467
• The event runs for 6 days + 18 hours, so natural Sanity regen supplies 1620 .  The weekly mission Top pots give an extra 200 per week, for a total of 200, or 400 if you saved from the week before.  Total possible of f2p regen is about 1820
• Natural sanity is sufficient for shop clear.

Event Stages With Good Drop Rates

• FA-8:  Oriron Cluster
• FA-7: Aketon

• Farming efficiencies (Source): the efficiencies for both of these stages are practically the same as main stage sources. F-8 has a higher drop rate for Oriron specifically, so it can be good if your primary need is Oririon.  Otherwise, there is no reason to farm the event stages from an efficiency perspective, but fine if you want to farm something different.
