Nidhogg EX gives you 235 weapons.
Palace of the Dead as well.
For 230 weapons, do A8 a couple of times (not entirely sure if the weekly loot lock is gone, if not, will take 7 weeks) to get the tome weapon.
Of course, Midas Savage gives you ilvl 245 weapons if you clear it, but that is quite a different level of difficulty compared to the other content.

There is also the Relic (which is 240 at the current final state), but if you don't like grinding, this one's not for you
