So, there's multiple things happening.Am I missing something or fuck up somewhere? Are they trying to encourage mutiple gem sets and swapping between fights, like if i had a pure fire set on slot 2 and used it that should have made it a breeze or something? Am I just being a dumbass? It feels like the game's gone from a fun and enjoyable experience to unnecessarily frustrating.
I've really enjoyed and loved these games since like, book 4 was new. I don't like posting something even semi-critical of them but idk what's going wrong now.
NG+ has the full set of enemies (and stuff like Auras), so combat does get harder than the old Book 1; at day 37 you're also still very early in the story, and you haven't gotten the upgrades (especially by end of act IV) that will allow you to take on more powerful enemies (Power level going up + Bella's shield buster).
It's definitely assuming you're filling up all 5 gem-sets and changing between them.
Sometimes, it's better to redraw all 3 cards if something is waiting that's going to screw with your day.
Make sure you're not on the wrong difficulty rating; the higher ones do get brutal now, and are really for people who love a challenging time on the paths.
Hopefully that helps.
