Marrow Shards is a powerful attack. With the Ossumancy 7/7, you essentially grant +100% cast speed. I recommend specializing in crit and ignoring bleed. Bone Knives 1/1 grants a whopping (.75*2) 150% hit damage on top of Apathy 1/1 and Dead Weight 5/5. Bone Splinters 1/1 and Marrow Caster 1/1 are essential.
Transplant is a powerful movement skill that will grant armor and damage reduction from Bone Armor 3/3, haste from Acolyte's Fervor 3/3, and CDR from Fleeting Form 3/3.
Bone Curse is a debuff that applies (Marked for Death) Sigil of Mortality 1/1 on-hit with Cursed Limbs 5/5. It deals increased damage with Oppressive Gaze 1/1 andAcute Infliction 1/1 and helps clear trash quickly with Ruptured Corpse 1/1.
Death Seal is a buff granting massive damage reduction and dps from Deadlock 1/1 and Corrupted Consciousness 5/5. Make sure to convert it from necrotic to physical with Corporeal Cascade 1/1. Death Seal unleashes waves of death more frequently with Tachycardia 5/5, and each one applies Condemnation 2/2's kill threshold.
Reaper Form is a transformation granting a second movement ability, Reap, with a separate cooldown from Transplant because of Unholy Dominion 1/1. While transformed, you'll enjoy stacking movement speed on-kill from Death Comes Quickly 2/4, increased cast speed Rapid Destruction 3/3, and increased damage from Soul for a Soul 4/4, Reaper's Curse 4/4, and Death's Door 4/4.

The most difficult items to find will be your wand and off-hand catalyst.
You will need a Dragonhorn Wand with the appropriate affixes as well as a Crystal Skull for its base crit and ideally with the desired affixes.
Viable Uniques
- Woven Flesh is an applicable unique that I used for about 1/3 of my time on this character. If you drop one with LP, go for it! If you're lucky enough to drop one with 2-3LP it's probably BiS.
- Exsanguinous is another unique I played around with that has some synergy with Hollow Lich 1/1 if you want to ignore leech and focus more on ward.
- Vaion's Chariot on paper look fun to use with your Exsanguinous if you can afford to slot both in without losing too much power.
- There are a few items centered around bleed if you choose to go for bleed rather than crit. I ignored them because crit is better but they are Valdyr's Chalice, Flayer's Pride and Symbol of Demise.
