I got really bored trying to LS my way to GM bushido, so dropped by the painted caves. The mobs there have decent hp and you can sit in the middle and they constantly come at you. Wraith form + curse weapon + momentum strike = really fast gains. The trick is to use a fast weapon that does just enough damage to keep you alive without killing the mobs too fast. I used a kryss with 20% DI. It sure beat the 30 min to hr between gains doing ogre lords.
