Well, my guy is more a gish (mixture of melee and spellcaster and debufs). His spellcasting as hexblade does not make him anywhere near full caster and invocations he got access to will make him at best a ranged debuf/sniping. He has more bunch of spell-alike abilities and mysterious powers and more smack things on melee for serious pain.<br/><br/>So going more a buff/caster for lamia could work better.
