How decoration shards and stars work
- Each decoration has its own personal shard. Placing it is level 1 and costs nothing.
- UR and SSR: level 2 costs 2 shards and level 3 costs 6. From level 3 to 6, each level has 3 stars. Each star costs 6, 18, 54 or 162 shards, and moving from 3 stars to the next level is free.
- SR decorations have no stars. Levels 2–7 cost 4, 20, 100, 500, 2,500 and 12,500 shards.
- Stars add a star bonus on top of the level’s base stat, listed separately in the game data. At 3 stars the base stat already shows the next level’s value.
- Universal Decor Component can be exchanged for most decoration shards: 15 per SR shard, 60 per SSR shard and 130 per UR shard in the data. Some event decorations have no exchange.
