Kinda funny bc I had 30 in like 4 or 5 stats (been a couple months since I played bc I thought the game was free so it took me all of an hour to beat the very short free version) and still failed every trial.
Kind of proving my point, you spread yourself too much : 30 is the bare minimum for an option to be potentially successful and you would need to know the Trial well. (Though some of the options are obvious)
The Trials are meant to be an optional challenge, they are not meant to be easy.
The game even outright tell you to be careful the first time you are losing points in a stat if it's neglected too long, but some players still raise every stats at the same time in attempt to see everything in a single playthrough, and that's impossible.
Or if they are like, they get the stat drop message and am unsure what that means for the playthrough and feels like it's potentially detrimental so they don't let it happen. I had 65-68 in int and was still absolutely trashed and was confused the entire time. Honestly I was convinced you're supposed to lose unless you have a perfect playthrough until now
