You can have total of five pets, but only one under your control at any given time. The others will have to be stabled.
Tamed creatures will respond to the following commands:
Heel! - creature will come to you and remain at your side.
Guard! - creature will attack any creature it sees attacking you.
Attack! - creature will attack any creature you target for attack.
Stay! - creature will remain in place.
Release! - creature will return to the wild, vanishing.
Move! - creature will move from it's current location.
You also have the option of boarding your pets in one of the Oberin stables, located in major cities. The following commands can be typed in while you are in the stable:
Stable - puts your pets in the stable.
Claim - removes your pets from the stable.
Your pets will automatically return to the stable when you log off or if you die at PvP.
Pets boarded in one city may be claimed from any other city's stable.
Water creatures, such as sea turtles and water elementals, cannnot be stabled.
Tamed creatures will only remain loyal so long as they are not hungry. You must feed your pets to keep them by your side.
Example: Type in "/pet1 Zarn"
Then you can use commands like:
"Claim Zarn" or "Stable Zarn"
"Zarn stay!" or "Stay! Zarn"
