What are the best cash shop opponents to unlock (best loots, exp, etc.?). Obviously higher tiered give away better items, but which one's are the best "bang for their buck"?

I want to stock up on opponents while they're back.

I hope that makes sense.

cindiliocks, bear head bomb flamagia, eternal flame Crithbolcan, aftershocks scroll Sophie, paintbrush blades Meatslab, Cronus Blade Mutant Scientist, Unstable Sample Syringe

all of these are staple gear I use all the time.

These are all the ones I unlocked for weapons/exp:

Crithbolcan challenges you to a fight in the Battle Coliseum! Tatuvichwa challenges you to a fight in the Battle Coliseum! Vile Carrier challenges you to a fight in the Battle Coliseum! Baenwurath challenges you to a fight in the Battle Coliseum! Slaughtersaurus challenges you to a fight in the Battle Coliseum! Decidiwi challenges you to a fight in the Battle Coliseum! Sophie challenges you to a fight in the Battle Coliseum!

These are the ones I've unlocked in the past for the best loot drops: Forj Matriarch Series Mad Scientist/mutant scientist Meatslab Series

Awesome thanks and . I will look into those opponents.

Thanks for the tip on Meatslab. Was going to pass since I'm far from able to win the blade, but I had forgotten it was a series! ;D

Oh yes good! The forj is a series as well and the mad scientist unlocks the mutant scientist :D
