Also, you can spam save at the beginning of the fight to maximize your critical hits. The combat RNG seems to be on some sort of predetermined track, not a true RNG. For each turn, each character attack with a specific weapon in a specific sequence will result in the same outcome when played from the same save.
eg. You've saved at the start of turn x. If an archer lands a critical hit with a silver bow on turn x when he's the first to attack, you'll get the same result if you load the save and he's the first to attack with a silver bow on turn x. Then you spam save to see if any of your characters can get a critical hit with one of their weapons when they're the second to attack. They'll always get that crit when attacking in the same sequence when you load the save. And so on. Definitely time-consuming, but it ain't cheating if that's how the game works.
