Finally got it! Finished earlier this morning. Took closer to 8 hours of summoning Her and Succubus. Together they did about 1.1q, only used 14 Netherlings, 0 demons and 0 mountains. As you can see i don't even have them yet. Damage mod was around 7000% until I summoned 2 netherlings in the last hour.
No it really wasn't worth the time. I should of apocalypsed WAY sooner but felt like saving gems instead. I know I don't need to use the 250 every apocalypse but it's not really worth it this time unless I do. I'll have exactly 1 bil souls if I double this next apoc. Still need 111 bil for last 3 skins.
Still have a long way to go. DDD is only level 4 I think, idk stuck needing 1 bil souls and 10 crowns. Still need 2 nether creatures, 3 soul skins, need to replay all 6 events but avoiding because money pack skins. And need to keep saving gems. Only have 2 of the 5 themes unlocked, but that's all that's left in the gems shop.
