Grocer Avia:
Automatic hunting is a function that let's you automatically target the next monster and contiinue hunting.
Automatic hunting function includes such options as distance to target, look pick-up and Manner Mode that prevents the character from attacking targets that are attacked by other players. During Automatic Hunting the character uses their basic Attack.
If you press ALT+K, however, then drag any non-buffing skill marked with two green arrows in a circle from the Skill window to the Shortcut and click it with the right mouse button, the character will attack using the assigned skill.
Same goes for buffing skills. If you put a buffing skill to the shortcut and click it with the right mouse button, this skill will be automatically used at the right moment.
