Pet help?

[Alberel]

Open up Pet Actions and hotkey the "Sic" action.
It tells the Pet to attack a selected target.

If you're using emerald carbuncle please never use the Sic command in group content. The knockback is infuriating for the rest of the party and you need to get into the habit of using Obey so that you can selectively use Contagion when you unlock it.

Once you have Ifrit you can have him on Sic as long as you're not concerned about stun immunity as he does significantly higher damage when freely using all of his skills.

But yes, Sic and Obey assign a target for your pet. Just please be sure to understand when to use each.
