Whats the difference between a pet and a follower?
A pet is a summoned creature. He lasts only as long as the caster can keep the spell alive. He is not equipable and not levelable. The strength of the pet is dependant on the spell casters stats and the spell he is using to cast the pet with. Pets will not cause any experience penalties. A pet is completely loyal. You may summon multiple pets at once granted you have the power to do so. Example: just as an anarchist can cast two continuous flame streams at once a summoner can cast two pets at once; in either case they will last as long as the spell caster can keep the spell alive. A follower is a permanent creature that is bound to you when it is at its lowest level. You will have to level and equip your follower(s) as necessary. You may have multiple followers at once. A person who is level X and has a level Y and a level Z follower is considered to be a single entity of level X+Y+Z. Followers are completely loyal.
