Conversions and instant Runestone grants
Element Runestones may be converted 1:1 into Gourmet or Party Runestones. Whispering Deer Girls may be converted into Gourmet or Shining Star Deer Girls.
New Deer Girl purchases do not require Alchemy time. Grants use the current output of a 100%-efficiency Hero as the baseline: 2.60 Runestones per hour. At 300% efficiency over 500 work hours, a newly purchased Gourmet or Shining Star Deer Girl immediately grants 3,900 matching Runestones.
Availability, application, and expiry
- Each Deer Girl faction remains capped at 1,000. Whispering Deer Girls are sold out; Gourmet and Shining Star Deer Girls remain available while supplies last.
- Submit a synthesis application during the campaign. The application channel will be announced separately, and 342C distribution will follow 342C operations scheduling.
- At campaign expiry, all Deer Girls and matching Runestones that were not included in a submitted synthesis application will be cleared automatically.
- 342 Games reserves the right to interpret the campaign rules.
