I Need You, Math's Mans!

You gotta give us some more info here... Like are you just talking about daily rewards + new maps + Quest orbs? Or are there chain challenges etc. you haven't cleared on lunatic just yet?

However, if you are referring to the Halloween banner as I believe you are, around 25~ orbs for October quests. I'm assuming there should be another Tempest Trial+ this month so thats another 30 or so. New heroes coming out = new maps = 20 orbs. Daily orbs for those new heroes + halloween banner (when it gets here) = 26 more. New Rival Domain every week = 1 orb a week for clearing the lowest level. Garden map in 4 weeks (maybe 3?) I believe is the one giving 5 orbs for clearing.

So yeah, you should clear around 100+ orbs by the time halloween banner rolls around, not accounting for events like 3 heroes etc.
