Good guide! I want to ask how strong it is in version 2.1

I recently got "despondence" and completely unlocked it, but I don't know which BD to use it. Please tell me what I should do.

Hello, sir, I'm at level 140 and have collected all the equipment you said, but I haven't used them yet. I paid some TG for this, but I don't know whether I should use store Mo or those rare Mo that fell on them?
