1. Auras - Consult with any other BS that happens to be in your party. Who ever has the highest level of Halisha runs it. Then depending on the majority of the other pets in the party run either Blood or Spirit.
2. Creature Stability - You should always keep creature stability cast on all pets that can pull agro that should not have it. Healing pets such as blue pixies and unicorns are key to keep this on. Above all else make sure if the cleric in the party has a healing pet to use it on their pet.
3. Crowd Control - The skill Nightmare when used properly can help your party out greatly. It has a slow cool down time so cast it often on non-chipped mobs.
4. Dual Summon - All pet classes should have 2 pets out as often as possible. Just make sure you do not keep unsummoning your main pet. It is a waste of the buffers mana when they have to rebuff it all the time.
5. Damage - Always keep your pets attacking with skills on auto. And after your character can do nice damage also but make sure you concentrate on the list above first.
