more now, than ever before, in fact. This is a summary of some good ones done off the top of my head...

Flails, I can think of trollmasters, crimson slumber, entwined evergreen, pestilence. There aren't too many flail users and these decent flails are usually more than enough to go around.

Polearms are quite plentiful. Mithril voulge, man-at-arms one, flaming and black bardiches, then a wrathing one which is nice for good aligns, and your basic scythe that can be bought in one of the weaponsmiths.

Whips, demon whip, diamond studded whip, willow branch, alligator skin one, chromatic one (if you ever see this), and several others I can't remember even though I have one in my possession.

Spears, again, plentiful. Staves too. There is an abundance of a basic wooden staff that is decent.

I suggest you spend some time exploring the past. The past is a good source for most of these.
