Even though losing the first Trial is not inconsequential, winning it is also not necessary. As for stats, though the Trial is difficult, you don't really need high stats to beat it if you know exactly what you are doing. Or you can just steamroll it with high enough stats.
Just sort of wondering what numerical value of skill you should roughly be at by that point.
I couldn't get through the first two doors with any of the options. Only by just spamming the knowledge challenge option could I brute force through eventually by I guess getting lucky enough on whatever hidden RNG was going on behind the scenes to let me through.
That's how I got through both first two doors, and then just lost on the third.
I mean, then I must've really really really missed something completely, because I used all the options available and they either just failed directly, or didn't do anything for me, leaving me to just have to spam the option that seemed most likely to work for me (thinking through the puzzle) over and over and over and over uncountable times till it worked.
