Fox only has two AoE, Fan of Knives and Pouch of Pain. Both of them are obtainable during 2nd job.
Only Fan of Knives is worth it since it provides a bigger AoE. However, the AoE is very weird. Old post of mine in regards of FoK.

Pouch of Pain's AoE is pretty small and is based off your current WT. Since your WT is most likely changing all the time with pot usage and stuff, your damage will keep changing too. :x
Charm's have quite a few AoE.
Cat = Siren Song and Sharp Scream (Primadonna)
Raccoon = Impelling Rage, Power Charging (Gambler), and Full House (Gambler)
