These are regarded as best melee spectres in game and have been for a long time, and for good reason. They have powerful basic attack with 181% more multiplier at spectre Lv.78 and 75% phys to cold conversion which can double dip with Hatred aura. On top of that they have Screech spell which increases cold dmg taken...wait but there's more: a gap closing dash-slam which triggers water geysers. They shred bosses even on a humble 6L. My build is pretty squishy and not suited for serious bossing, by all means edit my PoB and make it tankier to suit your needs, this is just a rough template.
