Farming Guide

Event Currency:

  • Event Currency only drops from Normal Event Stages.
  • Total needed to clear shop: 6275 (not including Furniture Parts)
  • Total from Event Missions: 1510
  • Total from First Clear rewards: 850 (370 from normal Stages 480 from EX stages)
  • Remaining currency needed from normal Event stages: 3915
  • Currency drops at a rate of 1:1 for sanity spent,  so 3915 Sanity is needed on normal event Stages
  • Sanity required for First clear of EX and Challenge mode: 240
  • Total Sanity required to clear the Store: 4155
  • One week of Annihilation will require around 125 Sanity.
  • Total Sanity required is 4280
  • The event runs for 2 weeks, so natural Sanity regen supplies 3360.  The weekly mission Top pots give an extra 240 per week, for a total of 480, or 720 if you saved from the week before.  Total possible of f2p regen is about 3840
  • Natural sanity generation will NOT be enough to clear the shop.  F2P players should try to save sanity pots from previous weeks and spend currency efficiently. 
  • Monthly Pack purchasers will be able to clear the store.
