Recently, some Scions of Fate players are complaining about the pet loyalty decrease issue, even when the players are not logged on.

However, this is not a bug but part of the game.
Pet loyalty decreases when the pet charm is in inventory, or equipped.
To avoid the loyalty decrease, the pet charms should be placed in the pet stable.
Currently, there is no item that has the effect of sustaining pet loyalty.
The only available item is Fallen Blossom, which is used to summon a pet again when the pet??s loyalty turns 0.  When the item is used, pet gains the minimum loyalty required to summon and players have to feed their pets to increase the loyalty.
