I present to you Anathema and Ifrit's Cudgel.

At level 35, Anathema -- which drops from a soloable mid-rank Notorious Monster -- boasts MP+24, Int+4 and Attack Magic Potency +17.

At 50, Ifrit's Cudgel -- which requires a party of eight and a lot of luck after even winning the battle to obtain -- gives Attack Magic Potency +20 as it's only relevant stat. Sure, it gives Fire Resistance +15 and Additional Effect: Fire Damage. But if played properly, either of those stats should come into play.

So, is there something I'm missing, or is my assessment accurate?
