Plan is to use the cat as first pet, start the battle with sword/warhorn.
Use f2 skill of pet and skill 5 of the weapons (get might and fury) then swap to longbow, skill 3 + skill 2 for high damage (by that time my pet has dealt vulnerability too) dealing high burst damage, then useing skill 4 followed by skill 5 to keep a gab.
switch pat to Moa, use f2 skill for another bash of fury once my first one runs out.
Normally that should allow me to switch to sword/warhorn again and use high speed of the sword and the warhorn to finish him of.
Elite skill as a final rescue. Signets used only in dire need.
