Is it better to get an Atk+9% Nab Cloth because its much cheaper than the Abusive STR 4(Atk +14%) enchant? I'm not looking to buy an Abusive Robe for its def pierce, although that def pierce against bio 5 demons wouldn't hurt. My GX currently has an FS 6 Atk +3% Nab Cloth, based on my previous research I thought this would be the best combination but now that I've see GXs use an Abusive Robe for Bio 5 I'm also now looking to get one if that's the best option for Bio5.
Basically my question is should I stick with my FS 6 Atk+ 3% Nab Cloth or get an Atk+9% Nab's Cloth or get an Abusive Robe STR 2/2 Enchant?
