Looks fun.
I may not be best to comment here as I have no sense of fun build, efficient killing is all that matters (Spike!)
I'm in a bit of a rush, Silver, so apologies if these are just quick notes and I'm a bit brusque
Mana Denial + Curses is actually a Tier 1 build (or near that), certainly not fun!
This is a bit of a schizophrenic build as I can see you're a bit of pyro, Silver!
So anyway, some quick fixes
-2 Ravenous Ghoul (6) - why? They are for
-2 Wall of Fire (4) - best with Dragonscale and Elemental Cloak, you need range 2 LOS and have Cloak of Shdows
- Drain Life (3) - 12 mana late game? So unreliable. Yes it bypasses armour but so does DOT
- Drain Soul (3) - maybe Skeleton Necro to stick poison, maybe mana denial/advantage build on a Mage Wand.
Are you Curses or Fire? Feels schizophrenic. Generally better to focus.
You have Elemental Wand yet you already have so many fire spells?
Wands (and Tower) are there to toolbox that perfect spell in match-up
Force Hammer, Surging Wave, Jet Stream etc (note all range 2)
If you really want flexibiity, go with 3 Rings (choose 2 according to match-up) and add
+1 Enchanters Ring (2)
+2 Enfeeble (4)
+1 Mongoose Agility (2) - with Cheetah Speeds and 4 Enfeebles and Cloak of Shadows, you get the idea
+2 Enchantment Transfusion (4) - gain ring bonus and safety of Cloak
+1 Force Crush (6)
+1 Nullify (2)
+1 Jinx (2)
You cast all of above + usual curses on your self for 1 each while kiting from his Slow elites, safe in Cloak of Shadows
Then once you have 2 Enchanter's Wardstones, transfer them all to him and reveal with all your banked mana
Checkmate
+1 Poison Gas Cloud (4) also helps when he's held in place but bit Win More...
You need to couple this with Full Blown Mana Denial
Siphon (as you have, always cast early)
Orb, Obelisk (against Swarm builds as Enfeebles are against Elite builds)
As well as 2 Crystals ad Battle Forge
I also like Mage Wand + Drain Power (but this manoeuvre is very tricky to get right)
Once you Transfuse Force Crush onto him, you Drain power every Early QC with Initiative so cannot remove it due to the Wardstones...
You are range 2 in your Cloak of Shadows (key piece, you need 2)
Don't worry about your conjurations being destroyed as you need the zone space for 2 Wardstones cast the turn you transfuse
All those Curses are banked actions for 1 big Transfusion action burst with sudden Mana Denial vs. Purge
That's the essence of Curse build
As you can see, the Curse build does not dabble in fire, you can't be a servant to 2 masters...
Because of Cloak of Shadows, I believe Mana Denial + Curses is actually best in Necromancer (you don't need Curse Weaving, just access to Dark, Cloak of Shadows and 10 channelling)
I was fine-tuning this build for the unfinished "How do you beat the Wiz?" thread but been diverted by design duties
Then you came along and brought it up!
Sorry gotta go but hope that's food for thought...
The first time you "checkmate" someone (especially with the Drain Power "soft lock"), just watch their jaw drop...
