~First And Final Line Of Defense V2.0~

If you need accuracy in the Ring slot, I personally think Ilabrat ring is better than Chirich +1. Not quite as much acc, but it gives +25 atk.

Honestly though, the best thing you can be doing is getting segs and RPing that Nyame. I know that sucks, but Nyame is legitimately amazing.

Another Ring Option for PLD is Beithir ring

Souveran head will get you killed in super high content. Still tweaking but this is what I use.
