Normally your first 6 star should be your campaign farmer - to enable them to start farming brutal 12.3 with 3 ungeared food champions. 

I don't have Cupidus either but looking at his skillset appears easily capable of farming.  Depending on the rest of your roster you may not 60 Kael or Athel ever. Definitely not Athel. Probably still will use kael.

Cupidus can't speed farm on auto unfortunately. His AI doesn't prioritize A1 even if his stats can make him do so. He can farm but it will only be a little faster than the starters. 

Kael is usually picked as an early farmer because he can also do CB pretty well, so if it's your first 6* I'd go with Kael over Cupidus. 

PS- Cupidus is Spirit affinity so he'll have a harder time with arena since early game arena is mostly Magic from all the starter heroes around.

Ok. I vote Kael then Cupidus.
