TL:DR = 7k ES, 75/75 block (NOT glancing blows), elemental ailment immune, crit immune, curse immune, chaos immune (CI), 27k armour, recover ~550 es on block (Aegis Aurora), ~2500 es gained on hit per second (Watcher's Eye), 20k phys max hit with no conditional buffs. 50% phys shift. *note* this is doing ~40mill dps, if you want more dps, you can swap the aegis for a malachai's loop which take it to ~60mill dps.

I titled it as moderately expensive because it uses Mageblood, Nimis, and crafted rares that you may or may not get lucky on crafting yourself. I've been playing and upgrading as I went, and prices are always in flux, so it's hard to give an exact amount but I'm probably ~500 div into this if you count what I've spent crafting in total.
I've been having a blast with my CoC scavenger build. Cyclone CoC is nothing new, but it's always one of my go to builds. It's been a while since it was super popular though, and even for the few people that do play it, most of those do it with Cospri's and cold skills. Another thing I notice with most of the CoC builds I do see, is people tend to go glass cannon on them. I don't play HC, but I don't like playing glass cannon, and I don't like having to filter out a long list of mods when I'm rolling maps. The only map mods I skip are ele reflect and reduced cooldown recovery rate. I can do ele reflect if I swap a flask. I could run the reduced cooldown, but it literally cuts the dps in half, it's doable, but feels bad. So rather than swapping flasks, or dealing with a feels bad map, I just feed those to the map runners if they're corrupted, or roll over them if they're not. I've also been running titanic treasure x 3 + essences on corrupted 8mod maps. If you've never run that combo, trust me some of those get stupid f'n tanky.
One of my favorite skills to use for CoC is Blazing Salvo. It doesn't scale well with flat damage, but it gives you a bunch of free projectiles. Most CoC builds don't have much, or any added flat, so that's not a big deal here. It also has the added benefit of being able to shotgun, which is fantastic, especially paired with a Nimis.
For those that might read this that aren't familiar with how Blazing Salvo works, at lvl 21 it shoots 8 projectiles, any single monster can be hit by any individual projectile on the projectile hit. When the projectile collides with either a monster, or the ground, it explodes for aoe dmg. A monster can only be hit by a single instance of the projectile damage on a single cast or trigger of the spell, but it CAN be hit by all of the aoe explosions. Unless you're dealing with a particularly large target though, it's not uasually getting hit with ALL of those aoe, it will be some number 1-8 depending on size and luck.
So the default behaviour would be cast 8 projectiles > take 1 instance of proj dmg > take 1-8 instances of aoe dmg. If you add a nimis ring, those projectiles go out randomly, do aoe dmg wherever they hit, then return to their origin, and not only do aoe dmg again, but the aoe they do is all stacked up at a single location and now it not only can overlap, but it will overlap.
None of that is anything specific to the phrecia event though, that's just defualt blazing salvo + nimis behavior. What brings the special sauce this time is scavenger. We get a free cloak of flame, 40% phys as ele is f'n great. That, paired with an eldritch implicit, shifts half your phys dmg off your armour and onto your resists, which funtionally makes your armour that much more effective.
We get a free void battery. For the first time ever we can cyclone with a wand ... sort of. Power charge + damage per power charge, on a CoC build .... f'n sign me up.
For the final one, the true unsung hero, fury valve. Let me start by saying pob is lying to you about this ascendency point. If you allocate this on the tree, pob will murder your dps and tell you you're now only shooting 1 projectile. At first glance you might think that it's right, but it's very wrong. The important part is that it says modifiers to the number of projectile. The extra projectiles on blazing salvo though are not modifiers to extra projectiles, it's default behavior of the skill. You're not modifying the skill to get 8 proj, it just f'n shoots 8 proj. So what actually happens if you take fury valve, with blazing salvo is that you shoot 8 proj, and all 8 of those proj can split to 2 diff targets, and if you have a nimis ... yes, all those splits and proj return and overlap.
The real magic though isn't in it's single target, it's in the improved clear you get from the splitting behavior. I've played similar builds to this in the past, and I've posted about them on this sub as well, but while those were very tanky, and had great single target, the clear was just a bit under where I'd have liked it to be. With the fury valve though, the clear is considerably better.
I know this is very f'n rambly, but that's why I put a TL:DR up top. I'm pretty sure I hit everything. Really I'm just thoroughly enjoying playing this and wanted to share it with someone, so this sub was that someone.
If you have any questions you can ask them here, or feel free to ask me in game if you see me on.
