MAX:
1. Echoing Strike
2. Mirrored Blades
3. Blade Warp
4. Blood oath.
1 point levitation. You can dump the rest of your points here.
Enough points in demonic mastery to reach lvl 20 with items so you can have 3 demons. But it's ok if you have low items and only reach 2 demons
1 point in hex: siphon will give you around 15 life/mana per death wich is good.
1 point sigil lethargy
Follow this, the maxroll guide is outdated. I have a similar set up except no hex siphon
Prebuff/hotkey cta (bc, bo), 2 defilers, psychic ward, hex bane, hex purge, and eldritch blast in that order. Use eth insight cv/or better eth archon staff as main wep, or an obsession/phoenix combo. Merc pride/cure/coh. Bind cursed holy freeze demon either tz heph/tz black lancer.
With this setup, you will be almost unkillable (except against dolls but with holy freeze demon you will have time to react if you accidentally tele to them), and have enough damage for fast TZ clearing/terror heralds
