However if a player in Harmony Island performs a Rune Run or combat Crystal Caverns, they cannot switch their team or rescue new pets except for Shivertusk in the case of Crystal Caverns. The level and strength of enemies are not affected in PvP. A player that is not a member can only have ten pets in their collection, but a member can have more than 100 simultaneously, and the stronger a player's pet(s) are, the stronger their opponents are in PvE battles These pets will not be rendered unusable by loss of Membership. The evolution of a pet used to affect stats, but in a recent update, pets are now all equal in stat growth, so evolution only affects appearance (except for Embershed). They can level up after winning a battle, if they get enough stars which makes some of them evolve. Players may have at most 2 pets in each battle.
Pets are used in battle and will fill in for the player in case they lose hearts or wish to switch for potential elemental benefits in combat.
