I've gone through some upgrades on my aura stacker in past couple of days. At first I kept just trying to get higher ES, but there isn't really too much point in going much above 5k (which is the amount I would recommend to easily do the feared). I decided instead to focus on getting more movement speed, which I believe to be the biggest thing the build is missing.

#Upgrades

Here is a list of the things I did and estimated cost:

• swap 1x cotb to unset ring with herald + assassins mark on hit (automate cursing): 3 ex

• since only 1x cotb, can now use trinity setup. controlled destruction + awakened cold pen -> trinity + hypothermia/faster proj

• add in 2nd herald, swap 2x medium cluster to Purposeful Harbinger: 1.5 ex (you can go for PH + rmr notable which is way cheaper)

• swap from bastion of hope to time of need. with 100% reduced effect of curses, I felt okay swapping from warding flask to grounding (now shock immune during flask and vastly reduced effectiveness of curses constantly): 10 regrets

• craft a new helm that is ES base. Was mainly going for ES + rmr + attributes + chaos res: 20 ex

• buy enchant service: 4 ex (save yourself the effort don't try to roll it yourself)

• torrents reclamation for speed: 15 ex

• determination corruption on prism guardian -> discipline corruption: 9 ex

• add in divergent determination: 6 ex

This brings us to +230% movement speed flasked which I think is respectable (nowhere near self chills 400% but its pretty good). When I run heists, I also swap precision -> phase run and dash -> smoke mine and run a 2nd quicksilver flask (for better uptime even when not killing mobs). With these changes, I reach +326% movement speed.

Also, I now pretty much always run faster projectiles, so I dropped divergent haste for vaal haste which you can always use for a nice +50% movement speed buff.

On a side note: YOU CANNOT USE TRINITY + PHYS SPELL. Hatred will juice up your cold damage too much so you'll never gain resonance in all 3. Also, the reduced effect of curses is really not that good and ideally youd want attributes (or an open suffix to aisling slam the attributes)

#Alt Qualities

I kind of forgot to cover alt qualities in my last post so I'll go over some of the more important ones now

##Divergent Haste

Gives a touch of proj speed which is nice if you aren't running faster proj. Gonna really cost you if you want to get the vaal version or lvl 21 (or god forbid both). This applies to all alt qualities; generally you should just settle for 20/20 and look to upgrade them much much later.

##Divergent Determination

Even after nerfs, it is still one of the strongest alt qualities. it just isn't stupidly gambreakingly strong. We still get ~20% more armor from this which is very nice, but it requires getting a more expensive prism guardian corrupt.

##Anomalous Malevolence

Extra skill effect duration for spark/blessings.

##Anomalous Molten Shell

This alt quality is really really good and super cheap; make sure to pick it up. We don't reach 50k armor (unless youre running alchemist's granite flask of iron skin) so this will basically increase our molten shell shield by 25%. Even if you reach 50k armor, I would still pick this up unless you have 50k armor unbuffed because sometimes you will just not have flasks up or not have charges.

##Divergent Dash

Great QoL. Much more consistent than phasing on kill (and I dropped stygian so didnt have abyss jewel socket anyways).

##Anomalous Dread Banner

The reduced damage is pretty nice. Dread banner overall is a really good aura for the build for the cost. ##Divergent Purity of Ice

You need to get it lvl 21 unless you have a +4 somewhere, and the only one I saw was going for 30 ex which is not worth it for 3% pen.

##Divergent Inspiration

More mana cost reduction, which reduces your needed clarity level for mana sustain and means you need less mana to cast spell (so can reserve more).

##Anomalous Spell Echo

Cast speed is a very strong quality. This alt quality made me prioritize getting to awakened spell echo much less since it makes the difference smaller.

##Anomalous Trinity

Cast speed good.

##Divergent Faster Projectiles

More proj speed always welcomed.

##Phantasmal Smite

Good, but not that much better as 20/20 than lvl 21 smite so imo not worth cost when starting out.

##Divergent Righteous Fire

Same as above

##Divergent Precision

Same as above
