I currently have 300~400 Energy in my inbox, and I used the 2x EXP booster (since it was going to run out in a couple days).

I can't B2, and I feel like I'm wasting energy which could be good EXP by doing B1 (and who knows how many energy I'll need to get all 50 pieces).

Is Conrad a good enough monster for me to get him instead of just farming EXP? I can faimon hell just fine.

I'm about mid game (can do giants b8, not 10 currently; trying to 6* some monsters to fix that).

EDIT: Thanks to everyone who replied. I have decided to go for it (as everyone said). I have 40/50 so far with 120 energy left in my inbox. I think i'll use those up on EXP now, then use the rest of HoH hours farming Conrad, so I can get an extra
