Hey guys, I gonna re-meld all my gears and got confused which mats I should meld in.

I'm happy with my Piety atm as if planning well, I never run out of MP.
For Spell Speed, I think it will drain my MP quick so I do not prefer it.

so for Crit, Deter and Direct Hit. Which one should I choose?
I'm quite confused so please give em some advice.

Thanks for rading and helping, mates.
