The crit damage mastery stacks with the crit damage from the traits for +60% crit damage, even if only 30% is displayed on the pet menu. When you increase your traits, pets DO receive the secondary stat benefits (condition duration/damage, boon duration, crit damage). Each point of pet attribute bonus increases power, precision, vitality and toughness of the pet by 10 points. When you increase your traits, pets receive none of the primary stat benefits with the exception of the pet attribute bonus. There are a number of pet factors that are not widely known, so I’m going to list them to start: If you find that any information is outdated, or have proof that something works differently, please let me know! I will continue to update it as I get around to it. Below you can find the beginning of my research. As a result, I decided to start a Pet Compendium. So I’ve been researching Hunter pets a lot, and found that even among “experts” there is a lot of misinformation out there.
