Solo? Shouldn't, anyway.
Other than that? VIT twins, AD weapon, max pdf armour with crit. DD (mix up with min.dmg if you do receive min. dmg from mobs 3/2 is a good ratio), costume+patterns (=240 pdef + 180 VIT) , HP absorb - time your aoe's for optimal leeching, along with your HP coil.. etc. etc.
