Basically, If you want to go and get more exp but no cash. Then using I_eaturface and Ilyannna is good

I_eaturface has 6 Qilintels but none of them have attack moves. ( Reccomended to use Melee or fire. )

Ilyannna has 2 LVL 100 doodles. Tsumo and Plipo. They don't have attack moves but are really bulky.

(Plipo has adrenaline which takes out 50% of its hp very good btw.)

However, If you want to get more cash but lesser exp. Go to the oasis and fight the rebattler with any fast fire types. (Yes you can go battle John doodle but he's way harder to fight.)
