Marauder
ChieftainCWS Expectations
First and foremost Cast when Stunned (CWS) build is focused on non-bossing content, although it can still do them at reduced effectiveness. This build excels at high and extremely high density content; think Simulacrum, Ritual, Ultimatum, Harvest, Strongbox, Abyss and so on. While I say the build is "AFK', that is more of a gimmick than reality. You still need to play the game, but you're able to walk away from your PC at any time.
CWS is also exceptionally low input, so if you're prefer low input gameplay there's not much better than this.
CWS peaks at mid-late game performance, and typically I play this build to farm significant currency in addition to 
Mageblood to then explore and try out new builds for the remainder of the league.
Mirage league discoveries
I'll add anything new here. This includes items, gems, tech and so on that is new to 3.28.
Recommend 87+ for swap.
Flask craft is arachnind tomb appparently
Recommend keeping 
Lori's Lantern on whenever it's small arena, and swapping back to 
The Hateful Accuser for single target (trial master/map boss etc)
Cord belt recommend 
Brink of Death annoint
Recommend 
Bound Flesh bloodline by For Flesh/Flame another chieftain node like, 
Ramako, Sun's Light, 
Hinekora, Death's Fury or 
Valako, Storm's Embrace. Whatever is cheapest. It acts like a temporary bloodnotch for big hits only. So it actually a lot against burst damage such as Fire 4, Small arena+ lightning 4.
Cull the Weak Support is extremely good for a high trigger support like 
Firestorm of Pelting.
EXTREMELY GOOD FOR SIMLACRUM EXTREMELY GOOD FOR SIMLACRUM EXTREMELY GOOD FOR SIMLACRUM EXTREMELY GOOD FOR SIMLACRUM EXTREMELY GOOD FOR SIMLACRUM
Mirage only Hybrid Endgame PoB: https://pobb.in/GUKwCsAq5x-g
keep in mind that gems have extra links in them, e.g malevolence has eternal blessing imbued and so on.
Imbue Gems Best to Worse
DD imbue tierlist: Cruelty > Swift affliction > Deadly ailments > Lifetap(?) > Burning damage > Sadism > Efficacy > Unbound Ailments
For Unearth, Imbue is bad, need 21 for even number thresholds. 28=29, 30=31, 32=33 and so on. 
Eclipse Support could be used with 
Elegant Hubris (Caspiro Supreme Ostentation) with an 
Awakened Empower Support 5 level 34 + quality Unearth.
For 
Righteous Fire, whatever you can get.
Mirage 3.28 Changes
Hinekora got adjusted, more proc rate, less damage. However, by endgame you were hitting DoT cap anyway so IMO not a big deal.
Bloodnotch nerf affected early decent amount (think 8 points to mitigate) but by end game 
Defiance of Destiny there isn't any affect by the nerf anymore.
Defiled Forces nerfed, but maybe exceptional support somewhere? Double chance to proc hinekora somewhat alleviates this nerf. Personally, it's a bit annoying but not the end of the world.
Leveling/Campaign
Highly recommended to follow pohx RF. If you're new to CWS or to RF please level with this.
If you're more experienced, you can deviated with alternate initial leveling such as Sunder until 19 for RF swap, or 55~ for swap then.
CWS Swap
No Bloodnotch
For the majority of people, 
Bloodnotch Isn't so quickly acquired at league start. Therefore, No Bloodnotch version is a gateway until then.
POB: https://pobb.in/JK3kksNTM0Fq
Follow this PoB carefully, and make your pantheons are LUNARIS and TUKOHAMA. Do not take Brine King.
Video Explanation on NO BLOODNOTCH swap.
Flask Crafting
Flasks are usually alt spammed, searching for +3 prefix + open suffix. You can finish them off at menagie to add on X immune during effect as shown in PoB. Ideally, everytime you alt spam Ignite chance suffix, always try to slam a +x flask when hit prefix as that will be a very good flask.
3% regen, 15% damage taken leeched as life are crafts found on the CRAFTING BENCH. These are unlocked by clearing Silo Map and picking the recipe by the boss.
Bloodnotch Initial Swap
Once you acquire Bloodnotch the main benefit is the ability to drop some defensives for some more offensives while getting tankier.
It's very important to drop the Life Recoup over 3 seconds mastery at this time and from now onwards.

Video Explanation on BLOODNOTCH swap.
Edit: If you are degenning at anytime for some reason and can't figure out why, just take Brink of Death to bandaid it from here on out.
Anytime Upgrades
I should first mention expensive upgrade options which you can swap in at anytime if you get your hands on them.
1. Defiance of Destiny
This amulet basically un-nerfs any change to Bloodnotch and makes you incredibly tanky.
2. Watcher's Eye
Vitality life on hit, Malevolence Multiplier, Faster Ailments are all great options to slot into the build whenever you can.
3. Good Jewels
Jewels such as Life %, max fire res, fire damage over time multiplier are all extremely good and you can stuff into sockets as you get them.
4. Tattoos
With shipment being swapped, Ignite % chance tattoos may be more readily available. So pick them up if they're cheap and you need ignite chance (you want 100% to feel good).
Midgame Upgrade 1 - Nebulis
POB: https://pobb.in/TEx-3of-uWyu
Basically, you want Nebulis asap. Last league was pretty for whatever roll, we just need to start and implicit don't matter.
Midgame Upgrade 2 - Initial Large Cluster
POB: https://pobb.in/fVUctZSotofO
When applicable, drop damage nodes for Large cluster nodes and start introducing Life %, Fire Multi AND/OR Fire max res jewels.
Video guide on Large Cluster Swap
The large cluster we want is 8 passive Fire cluster with 
Burning Bright + 
Widespread Destruction and a combination of 1 of the following 3; 
Cremator Master of Fire or Smoking Remains. For the 1 of 3 options, we never take this rear notable at the back of the cluster.
I highly recommend buying these jewels outright, however if you insist on crafting then your best bet is buying a ilvl 50-67 large cluster and doing some variation of fire mod spam and exalt. It's quite painful crafting this way.
Midgame Upgrade 3 - Triple Large Cluster Swap
POB: https://pobb.in/yv82lEh8PTQB
This includes mostly a tree restructure, and picking up even more jewel sockets and large clusters.
Video guide on Triple Large Cluster
Midgame Upgrade 4 - Prism Guardian Malevolence Aura
POB: https://pobb.in/1aIufgwcXUTx
Make sure to link 
Malevolence with 
Eternal Blessing Support OUTSIDE of 
Prism Guardian.
Within Prism Guardian, put 
Petrified Blood and 
Flesh and Stone (guess which stance we want). If you are running a Watcher's Eye with Vitality (life gain on hit), then you can squeeze in an appropriate 
Vitality making sure your HP doesn't drop below 55%.
In addition, keep your reservation topped off with one of the following.
1. 
Champion of the Cause (+ life mastery if necessary)
2. 
Leader of the Pack (annointed on new Cord belt)
3. Runegraft of Treachery (I prefer it tattooed on 
Infused Flesh mastery)
Video guide on Prism Guardian Swap
Midgame Upgrade 5 - Unearth DD Swap
Highly recommend Defiance first. It could feel squisher due to losing the helmet
I would like to firstly acknowledge the traditional owners of the this land and the gadigal people that you can skip 
Unearth + 
Detonate Dead if you prefer the 7L RF playstyle. Both versions have their benefits and downsides.
The quickest TLDR. 7L Righteous Fire + Detonate Dead of Scavenging is better at clearing low density very weak mobs because you can kill them faster than they can hit you to proc a DD. Unearth DD has higher success at single target with combined with. If you would prefer Righteous Fire check out my guide from last league, not much changed in terms of setup here.
Video guide here. Highly recommend watching.
The basics are using Unearth + 
Honourhome/ 
Viridi's Veil with a +2 AoE and/or +2 Projectile corruption linked with 
Enhance Support and 
Empower Support. This gives us access to level 30+ Unearth with level 6+ enhance to spawn a corpse with 100k life.
We then use Detonate Dead to explode this SPAWNED corpse. DO NOT USE Detonate Dead of Scavenging for this. In some exceptions, Detonate Dead of Chain Reaction can be used at the sacrifice of damage but for better clear and proc rates. I would only recommend this at ultra end when damage is no longer a problem for generic DD.
This is combined with The Hateful Accuser and we kill the phantasms spawned to then proc Hinekora, Death's Fury which when combined with 100% ignite chance gives us our single target damage.
Aspirational
(Post 3.28, i'd recommend skipping this for my hybrid setup, but it's very similar anyway. You can choose shield or 2nd sceptre)
I will mention in addition to the video, Mageblood is the last upgrade we want due to the nature of CWS and flasks in this build. However, many players choose to rush Mageblood so that they are able to reroll into other build later on.
If there are any additions found in 3.28, I'll add them here.
Hybrid Mageblood/Imbue
Ultra endgame aspirational for Mirage 3.28
Be very careful when looking at the PoB. Eternal blessing is on malevolence, cws is on punishment and each skill gem as +1 imbue.
PoB: https://pobb.in/GUKwCsAq5x-g
Shield craft explained here: Video guide
Gold Flask + 
Divination Distillate + 
Wondertrap = 300 Rarity
Use Jewel suffixes and implicits to balance attributes.
Pantheon also changes to Arakaali if degenning, and take less DoT damage on DoT mastery.
POBS
Mostly finished PoBs for now.
