instanced

bool Terraria.Item.instanced

If true, then the given item is instanced per-client.
Instanced items only appear on the client they were spawned on and are less likely to be replaced if a new item is spawned.
Instanced items do not exist on servers.
Vanilla uses this field for treasure bags and Defender Medals. tModLoader automatically handles this for modded treasure bags.
If you would like to make an instanced item, see any one of the following for examples:

• M:Terraria.NPC.DropItemInstanced(Microsoft.Xna.Framework.Vector2,Microsoft.Xna.Framework.Vector2,System.Int32,System.Int32,System.Boolean)
  
• M:Terraria.GameContent.ItemDropRules.CommonCode.DropItemLocalPerClientAndSetNPCMoneyTo0(Terraria.NPC,System.Int32,System.Int32,System.Boolean)
  
• F:Terraria.ID.MessageID.InstancedItem
  Defaults to false.
