Arcane
Arcane Accuracy is good, but PA allows you to hit targets flat-footed regardless of their buffs, abilities, etc, and AA doesn't stack with many other effects.So is Arcane Accuracy. And Prescient doesn't do much if you use Shatter Defenses or are Invisible to the enemies. Still, Eldritch Archers need to make do with it.Prescient Attack is basically budget-Dimension Strike and you can get it much earlier
It's a boss killer ability. Many bosses see through your invisibility, are immune to fear, etc.
If your target is flat-footed and you built your character/team correctly, you will hit them easily.
Of course DS is good too once you unlock it.
