Yeah I did that, just started A5 and ate the Vescavor queen. So I can keep going, good to know.
I'd make a save in any case, as stuff can bug out or fuck up before major choices like these.
Keep in mind that I haven't gotten that far yet myself, so I cant 100% say if you get to choose after consuming the queen, it just seems weird if they railroaded the last part of the game like that because of choices you made earlier. I'm keeping a few Mythic Paths for later as I heard they're either eintirely buggy or parts of them aren't working properly, i.e. Trickster seems to have a lot of Epic Tricks not working as intended. I'm not gonna play Azata cause it has a shitty scaley companion, and Lich forces you to sacrifice a companion. Too bad you cant romance Galfrey as a lich, or I wouldve gladly sacrificed her, but I actually need the romanceable companions in my party as they all serve a specific purpose.
At least Demon gets to bone Nocticula, but the powers are just too sucky. Not even sure if some of them are working, just testing Kalavaku Aspect and it didn't seem to add the 2 damage per die to spells like advertised at all. It's probably the most interesting path from a RP PoV due to what Act 4 plays like, but when everyone else gets fancy shit, playing something that has essentially no bonuses whatsoever until Mythic Rank 7 feels really damn disappointing.
