Body Amor Question

Okay so I’m at tier 6 duel wiled with blue mage spells. Armor needs +13 duel wield to cap it. I’m at +14 in armor. Should I keep my Ademar Jacket +1 to stay capped or should I put on Maglience Tabard for the store tp +11? I’ll lose 6 points of duel wield if I make the switch. Is it worth it?

Depending what you're doing adhemars glasscannonness will cost you dps in debuffs and damage.

I also don't know where you got 13 from.

Reiki Yotai + Eabani (or Suppanomimi I guess) and call it a day, right? Sacrifice far fewer defensive stats and also RY is way more comparable to other belts imo

As noted above, take some time to read about dual wield and understand how it works. You are likely way over cap and actually hindering your overall performance greatly by the sounds of it.

Feel like OP pulled this up before. 1st off you shouldnt be anywhere above T4 DW, you're blu so capping magical haste isnt a regular issue so you only need either 11 with DW3, or 6 with DW4, anything more is just dropping your TP gain for no reason
