There's definitely the type of RNG that can fuck your entire playthrough just coz it felt like it. Even if you have the knowledge and have everything planned well you can still get caught off guard, one example is getting ambushed by bandit in the starting city, Noer, where the rural place is usually pretty cramped so you'll oftentimes get surrounded. One counter example is by increasing Lona's Weak stat to 50+ and make those bandits try to rape Lona instead of attacking her, that allows you
to instigate a fight between those bandits and seize a chance for escape. However you can still get fucked by the RNG stun that comes from the bandits' light attack, or even be surrounded still, so it's not an entirely foolproof method (you can alleviate the stun effect through shielding).
The RNG isn't as prevalent as in DD, but it's still enough to get you fucked regardless of your strategies mainly because of bad positioning and stun.
