I don't know where Donjo came from but everything he said is false.

Here's my advice: Get the crafted chest, gloves, belt and shoes, meld them to the max with accuracy, det, etc.. You should have MORE than enough accuracy and plenty of DPS till turn 8 with Allagan Baghnaks. Now, if your group allow you to get the items from coil in order to get your Glanzfaust weapon, then there is where you should spend your soldiery.

You definitely don't need wave patas, nor wasting your time getting the mirror in order to upgrade it to tidal wave patas since it is shit anyway.
Also the 400 SS required is another broscience circulating in this forum.
