New Spiritmasters (and all pet classes from any game) have a distinct tendency to play in one of two ways. They either treat their pet as nothing but added DPS, or they take on the role of pet cleric. Because of the order that spells come to you in Aion, becoming a pet cleric isn't really a viable option in the beginning. By the time you do get the ability to heal your pet at level 16, hopefully you'll already have your own play style and won't fall into that trap. Avoiding the first is going to require some effort for some.The first pet you'll receive is the Fire Spirit. This floating mass of cracked lava may not be quite at the top of the food chain in terms of hit points (though he is close), but if you're looking for a pet that's able to keep mobs off of you with its taunting abilities, there's no better choice than this guy. It's for this reason that the Fire Spirit makes a good first pet.
