This is my current set. It works really well, but there are others that work too. I have three Lamordia weapons for the off-hand: one with Salt, one with Leg Affirmation, and one with Vulnerability, since I often play High Reaper solo or Short Manning. The one that has vulnerability (for bosses) is Slayer of the Living, the caster weapon of the Lamordia raid.
Weapon1 Warblade Dripping y ash (Facet of psionic intrusion, Ruby devotion)
Weapon2 Lamordia: Melan: Spell cost reducion, Dol: iFire. Mise: Fire spellpower, Woeful debuff (orange Meridian) (purple Ruby radiance)
LGS gloves (skill competence+insight; spell points profane + insight)

Bracers: Lamordia raid (Moon: PRR): cha, qcha, PRR, woeful: firelore (Green Resistance) (yellow set2 Esoterica DC)
Ring1. Bound Elemental Air. Air. Electr, Attuned air, SFM (blue Dodge) (yellow deathblock)
Ring2. Bound Elemental Acid. Acid, Acid, Attuned earth, SpellPenetration (yellow gEvo) (green greater Nec)
This set works very well, but there are other combinations that do too. I use Burning Blood and Thunderstroke, plus the acid DoT, so I'm interested in having decent acid and electric spell powers (although I only have fire and force maxed out).
