Lack of accuracy causes a lot of pain and suffering for you? Right here, right now we have special offer! Just use Scordeo accuracy exploit.
All you need is to be a priest or have a priest in your party which is also able to become Brilliant (the easiest way is another partymember to be a cipher), and enchanted Scordeo's Edge (Adaptive + Blade Cascade).
You just hit anything in battle with this sabre while the priest get Brilliant buff and start to spam Salvation of time, wait till Blade Cascade procs (if enemies are about to end, just hit your partymembers), once proced, SoT prolongs this buff (among every other buffs) as long as desired. So you have 2 buffs: one of them gives you up to +20 acc and another removes all yours recovery (so you attacks everything like a hurricane!). After battle end, save + load. Then, what you see is, that 2 buffs merge into one. Magic, yes! Dont stay, go to another fight, annihilate everything. During next fight, hit anyone with Scordeo again 10 times and it gives you +20 accuracy again! Yay, more accuracy. Dont forget SOTing it. After batle end, save + load. After thtis.. yes, you got it. Raise your accuracy sky high. More fights, more accuracy, more damage, more fun. Especially in location with a lot of separate fights (DLCs are the best places). No more suffering, no more pain (only for enemies).
