Left click is the ordinary button for the attack and right click is the pounce, and the c attack can be used in a pack with more than 2 raptors, the raptor pack call buff lasts 45 seconds and the pack buff can increase attack speed, damage output, resistance to damage and movement speed, would recommend using the pack buff when your in a tight situation, would recommend for small boss fights just use ascendant raptor saddle above 250 armor points and leveling health and melee
