Kallus2 Lists?

yeah, you don't really have anything in the list for setting up for the feat. but it sounds like you didn't really need it in the game either. raeks are great for that if you want to stay in theme. his own spell is great for it, but rarely wants to spend the focus to get it off. i personally like him in ravens of war, as ambushing grots are a great battle lust target, raptors play to the hit and run theme, and striders are useful for jamming, and thereby lighting things on fire.

swordsmen are great out of theme, as is azrael. i have not tested croaks yet. i can't find a list i like a lot with them.

i like your list though, hit and run with the angels, hex hunters can hex bolt or shadow bind heavies that have crippled by the angel. he is a very versatile, options heavy caster. so i think a lot of it comes down to figuring out how you want to play him, and building the list towards that. and that means some of his kit will be used less often in games.

My preferred method to set stuff on fire for the feat is jamming Striders (Blades or Scouts are both fine really, I prefer Scouts as they can spread out more), with Incubi waiting to pop out. Slap on Blazing Path and your opponent will often run into situations where they whiff on a Strider and end their turn on fire, or kill a Strider and if its their last attack, get set on fire by the Incubus that pops out. Failing that, Raeks make wonderful feat enablers thanks to the field marshal. Manuever safely into a heavy you want to tag and charge with something that before then was way safe back.

For this reason and a few others I really don't like Kallus2 in theme right now, as none of them quite get the mix right. I usually like Typhon with him since he is ridiculous with Overrun (both triggering it and benefitting from it), hits stuff hard enough most of the time (since Kallus can't buff beast damage himself this is important), and is hardy enough with his DEF/ARM/Excessive Healing.

Ravens of War is probably the only theme I'd like him with I think, since he can bring good cheap infantry for Battle Lust, enough decent warbeasts that can make good use of Overrun, and get enough free points to feel like you're not gimping yourself.

I've wanted to try him with the Blight Bringer and infantry, but it feels like such a trap when Overrun is such a comparably flexible and amazing spell for the battlegroup. I think he could definitely do it I just have trouble finding a compelling reason to do so, especially when if you're going to bring a gargantuan, the Archangel is a much better pick in my opinion for him anyways thanks to its native high SPD and P+S. My very first Kallus2 game I got to have my AA a solid 34" up the board killing the enemy's Hyperion and it felt damn good (granted my dice went cold and I didn't actually kill the Hyperion and it cost me the game ultimately but that's not my necessarily my fault).

But, then again it's a for fun list so who cares anyways right? For me my for fun BB list is with double Raiders instead (mostly because POW17 weapon master feels like overkill and flight/spd 7 is just so superior in every way). Also don't forget that Prey no longer does +2" on your Prey target in Mk3, so they're actually only charging 11". They do THREAT 13" thanks to reach at least, so if you meant that, then my bad.

Yeah I was just making the distinction between threat vs charge since it is a minor difference and I have a bad habit of being pedantic. Back on the topic though I still can't think of a good reason to do Warspears in their current state with Kallus2 even in a goofy list, I'd just be too wary of them dying to guns on the way up as usual. Grotesques can at least hide in forests and Assassin CMD ranges.

Given that the Legion community has had some trouble figuring out Kallus2, and it got me thinking that he probably favors a complex treatment rather than trying to find raw efficiency (even though it looks like he has the tools for that, it really limits his kit's potential, imo). That said, I put a list together over lunch that focuses on a more complex design strategy, and wrote out my thoughts on it, below. Disclaimer: I typically field beast-heavy lists, and have yet to pilot this (as I literally just built it), so this is a bit heavy on theory-craft.

Kallus, Devastation of Everblight - WB: +28
- Seraph - PC: 14
- Angelius - PC: 17
- Naga Nightlurker - PC: 8
- Raek - PC: 8
The Forsaken - PC: 4
The Forsaken - PC: 4
Grotesque Assassin - PC: 0
Grotesque Assassin - PC: 0
Annyssa Ryvaal - PC: 8
Blighted Nyss Raptors - Leader & 4 Grunts: 18
Strider Blightblades - Leader & 5 Grunts: 10
Grotesque Raiders - Leader & 9 Grunts: 12
Fuel Cache - Steamroller Objective
THEME: Ravens of War

The general idea of the list is to balance Kallus' interest in both infantry (40 pts for 2 free solos, up to 64 pts w/ solos) and beasts (47 pts), while maintaining his interest in pressuring assassination, triggering fire on his feat, extending threat ranges, and having some scenario game. Trying to manage threats against this list is... challenging.

Both the Blightblades and Raiders can ambush, and the Raptors and Annyssa can run 18" on turn one, with only the Forsaken and Naga being SPD 6, and everything else SPD 7 or 9. On top of being very fast and aggressive, the opponent will also lose AD (if they have any), further setting them back on board presence. Both assassins, Blightblades, Annyssa, and the Raiders have or can gain stealth, and although Legion can see thru this, immunity to fire across a whole army is strong in most Legion matchups. Everything is also relatively high DEF, with the exception of the Raiders' terrible statline. Speaking of Raiders, when they get Ambush, stealth, potentially +3" threat, Battle Lust, and native Gang, they can add some damage threat that would normally be assigned to beasts. Forsaken manage fast beasts, are terrifying with 5 fury and Battle Lust, and they can also manage jamming infantry or focus/fury heavy lists to some extent. Raptors are generally strong with Kallus2 because of their high base accuracy (Annyssa adds to this), ability to get ranged work done (esp. vs living), and giving them Battle Lust means MAT 6/7 with 3d6 to hit and 5d6 PS 10 at a 13-16" pathfinder threat; they also have impact attacks that benefit from Battle Lust. On top of all that, all the beasts can Overrun around, cav models can reposition (Kallus, Annyssa, Raptors), and the Assassins have sprint (and grievous wounds).

Beast-wise, the Seraph provides a DEF debuff, and slipstream to further extend threat ranges on a variety of models, on top of being a serpentine model against knockdown-heavy lists. The Angelius is the second serpentine model (of three) that can help shield Kallus against knockdown feats and the like, has an incredible threat range, and can be either a great assassination piece, a ranged threat, a poke in the eye for a hard target, or a scenario piece. The Naga solves for some of Kallus' issues with defensive buffs, is another serpentine model, and can play midrange game fairly well; putting its animus on Annyssa can be pretty deadly in some matchups (Stormlances). The Raek can flank hard (up to 24" from Kallus), and with Overrun and leap they can get into some unpredictable places, setting up for the feat (allowing ambushing models to charge up to 16" off the side of the table).

Some alternatives I could consider would be dropping the Angelius and Annyssa for 25 points, and picking up two Neraphs - pretty solid with Overrun, but not very hard-hitting... so maybe not with Kallus2. I could drop Annyssa for a Raek, giving a better beast flank in exchange for the strong Stormlance counter and Raptor +1 to hit, or for two Deathstalkers to up the anti-infantry game (although, I think it probably has enough anti-infantry tech, and even if tough spam could be an issue at least the Assassins have grievous and blightblades might get a few crits). Looking back, I could also add a unit of Grotesque Raiders/Banshees in place of the Blightblades, but it would diminish the versatility a bit, I'd have to cut an assassin to make room for them, and they wouldn't get ambush; it would, however, give me a better points setup for putting in 1 or 2 spell martyrs...

A big fault in the list is having no spell martyrs to sling spells around with, but at one point each it really effs the list design because you can only take 3 and there are 4 easy points to spare (because while two assassins are cool, they're not necessary – it just allows for more flexibility and tactical value in approach with the ambushing unit being able to flank both sides and gain stealth upon arrival). Finding room for spell martyrs is probably my #1 interest as I iterate on it; and I really miss having incubi given that I'm running 2 ambush units.

Kallus2 is definitely a pick your poison kind of caster. Pick one of the 2 or 3 strategies his card presents, and run with it. Can't do it all!

I like this list a lot.  Its probably the first one I've seen that tries to make use of Kallus' whole card.
I've seen dedicated Overrun builds and dedicated Battle Lust builds and this one has a nice mix.
