Go to the Yamotsu mines. Go past the Earth/Dull Copper elementals, then past the first room that has 1 warrior and 1 Earth Ele in it. The 2nd "room" has 2 warriors in it that respawn VERY quickly. Before you finish killing 1 another has spawned. I took Swords to 120 from 85 in 2 days along with Bushido from 95 to 115. Best place I've found for those gains due the the non stop spawn and the fact that you're always swinging with no pauses in between spawn times. I used Soul Seeker and didn't have to bandage once and never ran out of mana. Just honor each one and you'll be set.
