In no particular order, here are some things you can try. I haven't tested all of these. I think I eliminated Factions dependencies, but I may have missed some. Note that R/A Shadow Form Whirling and R/Rt Signet of Spirits spirit spam and even Destructive was Glaive and/or Vengeful was Khanhei feather farms are usually more effective than many of these, especially the R/A. That R/A is terrific, because Shadow Form is still OP.

Stockpile Decayed Orr Emblems, turn in during Halloween or Wintersday, sell points from items, or just sell the emblems if you find a buyer.

Replace Soldier's and Protector's with Lightning Reflexes and Whirling Defense.

Replace Soldier's and Protector's with Lightning Reflexes and Whirling Defense. Replace By Ural's Hammer if you load that template code with something else.

This might not work in Hard mode after the Jan. 5 health update; I haven't tried. I use a variant of this in NM Underworld.

Replace Brambles with Winnowing. You might need to play tag with the Aatxe, but they'll be blind and crippled, so the next round of traps will kill them.

Because you might want a Totem Axe sometime. Replace Triple Shot with some other attack.

R/E using Storm Chaser, Stone Striker, Armor of Earth, Earthbound or Blessed insignia, a +10 Earth shield, and Area of Effect Earth Magic can farm stuff. Might be able to kill the snowmen with this.
R/P with Spear and Beast Mastery can solo, but it's single target and thus slow. OK'ish for Nick farms.
Run into Fronis dungeon hard mode and kill everything.
