Arknights Chapter 15 Sanity Rebate Event Efficient Farming Guide
Detailed guide on efficient material farming during the Arknights Chapter 15 update's Sanity payback event starting September 16th. Presents strategies to maximize Sanity efficiency by considering the best efficiency maps for each material, farming priorities, future sight-based requirements, and alternative farming methods.
1. 💰 Sanity Payback Event Efficiency Analysis and Utilization Strategy
- ✅ Farming efficiency of the region update event is very high at 124% compared to regular permanent maps
- ✅ It is more profitable to farm as much as possible using Sanity restoratives and Originium Shards compared to subsequent events
- ✅ Great growth for newbies, opportunity to stockpile resources for veterans
| Category | Efficiency |
|---|---|
