My regex when rolling t17 and t16.5 maps. Feel free to edit and make it your own:

"!hey|fe a|f el|ced e|o al|gen|r li|efe|pet|ss are|wb" "y: (m|r)"

Budget items:

Watcher's eye with zealotry linger and zealotry damage: 1 div

Passable cluster jewel: 50c

medium clusters: 40c

random resist/attribute/crit multi/cast speed jewels: 150c

timeless jewel: 100c

Amulet: 20c

anoint: 95c

helm: 100c

gloves: 10c

boots: 1 div

belt: 10c

shield: 10c

Ring: 100c ish. Doesn't need the strength since my gloves have enough, but it's what I had

other ring: 1c

6 link sacred chainmail: 2 div (I spent about 3 div crafting mine)

flasks: 100c

wand: 120c (cheaper if you bless it yourself)

Runegraft of the fortress: 20c

20/20 vaal ice nova of frostbolts: 1 div

total: 12-18 div

Upgrades from here:

bottled faith: 4 div

Awakened inc aoe support: 5 div

BIS cluster jewel: 10-12 div if you buy one. Can craft for cheaper, but it's a pain.

Actual curse on hit ring. 4 div ish.

better gloves: 4-8 div

Better crit multi jewels: 4 div

power charge helm: 9 div

better chest: 15-30 div if you don't craft yourself

Expensive upgrades:

+1 power charge ring and kalandra's touch: 100-120 div

Focused amulet with +2 all skills and +2 cold, with either minimum frenzy charges or crit multi: 150-200 div

Note:

if you don't have a triple watcher's eye like mine, you'll want to take the crit master and armour mastery for reduced critical damage taken

It's up to you on whether you want to use profane bloom or Vile Bastion. Once my clear with ice nova is good enough, i usually spec into vile bastion, but I wanted to keep profane bloom here for the showcase so that new people to the build can experience how awesome profane bloom is. If you find yourself getting sick of stuns or dying frequently, try out vile bastion instead.

The 3 passive cluster jewel i'm using is just a random one I found that had decent passives on it. You don't need one exactly like this, and there are many better ones out there. See my current PoB for the one you'll want eventually.

I didn't use my 2nd curse at all in the showcase. It would have made the boss fight much faster.
