I've got Kael and Sinesha (thanks to feedback from this forum) up to 6* and fully booked and ascended. I'm still stuck at Stage 7 of Durham Forest in the Nightmare campaign, Level 13 of Minotaur, Level 9 of Spiders, Level 12 of Dragon, Level 11 of Ice Golem, and around Level 13 of all the Keeps. My Clan Boss damage is ~2.5M on Normal. I'm Silver 1 in the Arena.

I'm trying to figure out how to make progress in the game. After getting Sinesha up to 6* to go along with Kael, nothing really happened in terms of incremental progress. I'm still stuck in basically same places.

So I've now farmed 12-6 non-stop enough that I've built enough 5* chickens to get someone else up to 6*, but I'm hoping that hero will help me progress, at least in terms of gathering better gear.

So my real question is if Umbral Enchantress / Coldheart / Athel / Apothecary really going to make much of a difference, or should I hang on to my chickens and wait for a hero that will actually help me progress?
