Gray

=Graylings/Children= After evolving Gray, Gray creates a child of itself that operates similarly to having another pet. It can be one of three classes: Adventurer, Blacksmith, or Alchemist. All of which have a 0.8% * CL bonus. The Child's growth is equal to the Mother Gray's growth, and the Child cannot earn growth in Growth campaigns or in dungeon events; the growth of the Child will always be equal to that of the Mother. All XP gained by the Child is "sent" to the Mother Gray, and the two share the same Dungeon Level and Class Level.

Token Upgrade
You can use a pet token to get a second Child from Gray which can be any dungeon class (Assassin, Supporter, Rogue, Mage, Defender) unlike the first Child. The Class bonus is still 0.8% * CL. Gaining the second child will change the XP gain to 60% per child that is sent to the Mother, meaning a total XP gain of 120% if both Children are earning the same amount of XP.
