How much item level we need for the new content?

Well then you need 4 weeks for the weapon, i thought they would've changed the item you need to perm drop already.

It's kinda funny that the datalogs from alphascape savage are now farmable, but crystalloids from O12N are still limited to one per week.

The most readily available weapons that don't require crafting or spending gil are probably the i360 weapons obtained with sigmascape crystalloids. It might not be great but it's a whole lot better than the i300 one. Four repetitions of O8N take less than an hour and if you're doing anything at max level you'll have 1000 mendacity before you know it.
