I've have been doing some research on pet aug and thought I'd post them. Pet Augment effects have the Effect Pet Power Increase (x) where x is in increments of 5 usually. Most post seem to think x is the % increase over the unaugmetned pet. In my list I start with Level 1 being x=5 and each level x increases by 5. R is a raid mob. R? listed as raid but may be 1 groupable now by 70+.
