I'm gonna take Alweth's advice and ignore his own arguments.
Tri-Sword. Too strong for halflings. Basically pointless for everyone else.
+3 base damage per level was too good, so it got nerfed. +2 would be better. This makes it strong for all races, but not nearly as powerful as before.
Whurrgarbl. Inferior to Tri-Sword basically all the time. I liked the old +1% per kill with 5% base. This would be strong for all races and be relatively balanced. It scales with your character, so you can't abuse its power.
