Preluding Lights- Event Operations and Farming Guide

Event Currency:

• Event Currency drops from any stage except for Annihilation, and Extreme Modes.
• Total needed to clear shop: 1840
• Total from First Clear rewards: 400
• Remaining currency needed: 1440
• Currency drops at a rate of 1:1 for sanity spent, so 1440 Sanity is needed
• Sanity required for First clear of Challenge modes: 60
• Total Sanity required to clear the Store: 1500
• The event runs for 1 week, so natural Sanity regen supplies 1680.  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 1880
• F2P players can clear the event on natural sanity.
• Shop efficiencies (source)

T3 Materials From Event Stages

•  PL-5 - RMA70-12

Efficiency: Do NOT Farm. RMA70-12 has an overall efficiency of .943, so it is overall less efficient than 4-9, so PL-5 is not recommended to farm for efficiency.  PL-5 has a sanity-per-drop of 51.58, where R8-9 has a sanity-per-drop of 52.29, so it isn't really better for speed collection either. source
