Your pet is not fully leveled up. Kill more enslavers to Max that affix. This is not a bug. Do not reroll anymore. Just kill enslavers to Max the value.
Ok thanks got it only needed to kill 3 enslavers and it buffed my affix
Never tought the affix buff was permanent lol i always tought my pet had stronger affixes for the level
Now if you buff an eternal pet to its maximum ( it’s a common misconception eternal pets don’t level through game play ) then your arena toon may have 6 to skill or talent on pet rather than 4.
