Pet damage takes two forms, white damage and yellow damage in game
Pet DPSing: Many people say that pet DPS isn't worthwhile. If you just let your pet auto attack that can be somewhat true, but if you work with your Cabal Alz pet and use their abilities carefully your pet's DPS will increase and increase yours as well. Pet DPS is largely self sustaining.
The secret is to build up your pet with talents and teach them new abilities so they can work on their own. Pet damage takes two forms, white damage and yellow damage.
White damage is from your pets regular auto attacks and is the base of your DPS. You can increase this by buffing your pet but it will stay very regular. (Pets also get a portion of your stats like AP or Sta so buffing yourself buffs them as well.) It may seem low compared to your damage, but over a long fight it can add up significantly.
Yellow damage comes from abilities like Bite or Gore. These are special attacks that use up your pets Focus and often have a cool-down. Most of these abilities are also restricted by your pets’ species.
Bite can be learned by almost all species, but only boars and ravagers can learn Gore. This means the pet you choose will determine how well they DPS.
Maintaining Your Pet: Pets require a lot of maintenance. You need to constantly keep them happy by feeding them, level them up and teach them new skills.
