Only around 13k myself, but I am interested to see how far the Beelzebub Rampage train can carry me. Between Beelzebub and Brynhildr, I have pretty good uptime on +attack and +multitattack buffs and with my passive boosts, I've got 3 characters that can auto-attack for around 6k per hit fairly regularly.

I'm really torn on whether I want to focus on summons or the weapon at this point. Would really like to get something other than the 30% R I'm currently maining for my summon, but I imagine the weapon(s) are going to be a lot more useful in the longer term.
