I have been wanting to make a Beastmen entry in this series since the beginning, and with the most recent update, I can finally do it justice. Skip to the lists if you're familiar with my posts, but for any newcomers: these builds are designed to be themed around the Legendary Lord's bonuses, gameplay, overall roster utilization (between all LL's in a faction), background lore, location, and starting units, in that order
. The entire point of these builds is to force, by means of fun themes, myself and perhaps others to utilize units in their campaigns that they may otherwise not. For example, I am personally not a fan of chariot units, but if I'm playing Settra or Khazrak, you can bet that I'll use them. Obviously, this all means that the lists may not be the best choice for Legendary difficulty, or multiplayer, but those players are not my target audience.
1) Khazrak the One-Eye
Khazrak on Razorgor Chariot
Wargor on Razorgor Chariot*
Bray-Shaman (Shadows) on Razorgor Chariot
Bestigor Herd x5
Ungor Raiders x4
Chaos Warhounds (Poison) x2
Razorgor Herd x2
Razorgor Chariots x3
*Wargor added per @MiniaAr
Khazrak grants vanguard deployment to Bestigors and Razorgor Chariots, stalk for Bestigors, Warhounds, and Razorgors Herds, extra charge bonus and bonus vs infantry for Warhounds and Razorgor Herds, increased melee attack and charge bonus for all melee infantry, and he increases the missile strength of Ungor Raiders while also granting them poison damage. Khazrak buffs every single thing in his army with the exception of the Bray-Shaman, and that's not even all of his buffs; I only included the relevant ones. The Bray-Shaman has the Lore of Shadows because Khazrak is the sneakiest Beastmen LL and has a lot of ambush success bonuses.
With Khazrak, I'd focus on attacking Men, mostly the Empire and Bretonnia, but starting with Tilea and Estalia, given the start position. I would take a route that would lead me to Middenheim close to last (regarding the realms of Man).
2) Malagor the Dark Omen
Bray-Shaman (Beasts), either mount*
Wargor, either mount
Gor Herd (Shields) x2
Gor Herd x3
Feral Manticore x2
Giant (Beastmen) x2
The Eye of Morrslieb
*Bray-Shaman added per @MiniaAr
Malagor's Harpies cause fear, which I value more than Khazrak's bonus for harpies, which is a charge bonus and bonus vs infantry. Malagor also has increased unit capacity for Harpies, and is called the Crowfather. I gave him a Wargor on a Razorgor Chariot simply to support him if he lands or to otherwise disrupt infantry that may not be subject to a Flock of Doom at a given moment. I gave Malagor the mid-tier melee infantry because his expensive units aren't as threatening as Morghur's or Taurox's. Malagor starts with a Manticore but more than that, as the only flying Lord, it makes the most sense. He also starts with a Giant (the best-looking kind). Malagor buffs the weapon strength and armor for pretty much all of the Beastmen's monsters, but I believe that he gets the more utility out of the Harpies, Giants, Cygors, and Manticores than the other LL's. Taurox's buff to Cygors is only armor, but Malagor also increased their weapon strength, which I would consider their most important stat after range.
With Malagor, I'd travel south/southeast, taking on Dwarfs, Greenskins, Tomb Kings, and Lizardmen. Bring ruination to all. I'm saving Malagor for TWW3.
3) Morghur the Shadowgave
Bray-Shaman (Death), either mount
Ungor Herd x2
Destroyers of the Drakwald
Ungor Spearmen Herd
Sons of Ghorros
Centigors (Great Weapons) x2
Groghooves of Wolf's Run
Centigors (Throwing Axes) x2
Chaos Spawn x4
The Vorbergland Broodmother
Morghur grants unique battle effects to Chaos Spawn and Jabberslythes as well as boosting their melee defense and weapon strength, which he also gives to Centigors. He is also the only LL to buff Centigors at all. I gave him the low-tier infantry mostly for the name of the RoR, which is an uncharacteristic choice for me honestly. "Destroyers of the Drakwald" strikes a very anti-forest vibe, right? Even though Drakwald Forest was mostly inhabited by men of the Empire, the Wood Elves care for all forests and Morghur has an intense fixation on ruining all of the WE's fun. That, and Morghur's army can handle having worse infantry with their other units and bonuses, especially in campaign. The unmounted Wargor acts as a bodyguard for Morghur. The Bray-Shaman has the lore of Death simply because it seems like the least worst choice between the four options. I haven't given the lore of Beasts to any of the LLs's; I have an unsupported idea that Beast casters are generally not themselves bestial.
With Morghur, I would hunt down all of the Wood Elf factions across the world, hitting Athel Loren last. The idea is that Morghur is corrupting the magical forests and weakening the Oak of Ages/Ariel before going in for the kill. His immunity to magical forest biomes supports this kind of a campaign.
4) Taurox the Brass Bull
Bray-Shaman (Wilds) on Tuskgor Chariot
Tuskgor Chariots x4
Butchers of Kalkengard
Minotaurs (Shields) x4
Minotaurs (Great Weapons) x4
The Bloodbrute Behemoth
*Wargor removed per @MiniaAr
Taurox's army is OP and there's no getting around that, so let's just embrace it. He buffs Minotaurs like nobody else, so they're a given. He also gets the Ghorgons even though Malagor technically buffs them more than he does. I've chosen him to have Ghorgons over Malagor because Malagor also buffs a lot of other units, and the RoR Ghorgon is very much Khorne-associated, as is Taurox. Plus, Taurox alone gets a +1 unit capacity for Ghorgons. The characters in the army provide armor-piercing, spellcasting, anti-infantry, and anti-large, in that order. The Wargor can also support the Tuskgor Chariots, which I've given to Taurox to fill a gap in his build and because none of the LL's buff Tuskgors, so I had to pick somebody. Having the less beefy chariot and mount option helps offset his power creep somewhat.
With Taurox, kill everything and everyone. Starting so far away from the other Beastmen lords makes any campaign direction rather unique for the faction.
That's it for the beastie boys. Let me know what you all think, and as ever, I am willing to edit the lists if a change makes sense. Just provide a reason for why you'd change something, and I very well may do so. I have never professed to be an expert or even particularly knowledgeable about the TT lore.
As a side note, I have updated the Dwarf list to include Thorek, and I intend to do the Skaven next.
