Farming Guide

  • Event Currency can be earned from any Stage other than Annihilation and Extreme Modes (similar to Operational Intelligence Event)
  • Event Currency [Quantum Firecrackers] drop at the rate of 1 per 1 sanity spent.
  • Total Firecrackers/Sanity needed to clear shop: 1600
  • The shop can be cleared with less than 7 days (6.66) of natural sanity.
  • Pure f2p players should have no trouble clearing the shop.
  • Although the event nodes have ok drop rates for their primary enhancement material, the drop rates are not significantly better than normal farming nodes, so players can proceed with normal farming plans.

AF-6 has lower efficiency and higher expected sanity / drop than regular farming maps, therefore NO GO.
