I have made a calculator for people to use to help complete the 2022 collection. Simply download or make a copy of the spreadsheet and input the current decorations you have into the yellow cells. Afterwards the green box will present you with the cheapest option to obtain a unique decoration and the correct decorider settings.
Things to remember
- Update inventory after each unique decoration when using decorider.
- Update inventory after opening small boxes from missions
- Save antiduplicator charges for last 14 decorations
- Once cost in green box reaches 3500 it is best to use the 2000 shard anti duplication setting + collection setting + deco type setting
Thanks and hope you guys enjoy and good luck on completing your collections.
