This pet is a nice upgrade from the level 7 pet. For starters he is level 11. His max hit is 18 and his max kick is 10. Bash still seems to be a max of 1, I am unsure if this ever goes up but i assume with higher level animations it will. The level 7 pet hits for 16 max and max kick is 8. Both the level 7 and 9 pets can double attack although this one seems to do it a bit more often. This pet is also the first one who can hit magic only creatures like ghouls and wisps on his own.
Once i got him I was able to keep the small orc camp in Nek forest clear without clarity while solo. The old pet almost required me to have clarity to keep it clear at level 8. This is on progression server with no newb armor yet so almost no stat buffs at all. The basic idea is pull with chaotic dd spell and then hit him with it again and then med up through rest of fight. the pet generally takes care of it. if they are even and my pet was not full health when the fight strted i pulled with slow and then hit the two dd spells. The pet almost always grabs the aggro away. On occasion i would have to give him a second to establish the aggro and then i would med.
Hope this helps.
