When you first get your pet, you will want something other than Cower or Growl. The two main attacks most early pets are trained with are claw and bite. However, which is best of the two in different situations?
Damage per second
108 - 133
Claw 9 (Twice)
108 - 152
54 - 76
As you can see, bite does nearly twice the damage as claw, but takes twice as long to cast, while claw hits twice in that time, causing more damage, but using more focus.
So which is the most effective?
