The new Sons of Behemat Spearhead is the Stone Lobbas: three Rock-hurler gargants, one of whom leads the others. You build it from a single box of the new Boss-stompers kit, assembled as Rock-hurlers. It’s the smallest Spearhead around, with just three models, and it suits players who want a quick-to-paint force of big, characterful models that throw rocks and then wade in.
The Stone Lobbas arrived with the new Sons of Behemat battletome in September 2026. There’s also an older Sons of Behemat Spearhead built from three Mancrusher Gargants, which we cover below. For everything else in the new book, see our Sons of Behemat battletome guide. New to Spearhead? Start with our Age of Sigmar Spearhead guide.
What’s in the Sons of Behemat Spearhead?
There’s no separate “Spearhead” box for the Stone Lobbas. Instead, the force is built from one Boss-stompers box, which makes three gargants as either Boss-stompers (melee) or Rock-hurlers (ranged). For Spearhead, build them as Rock-hurlers.
| Unit | Models | Role |
|---|---|---|
| Rock-hurler (general) | 1 | Your leader. Gains the Hero keyword in Spearhead. |
| Rock-hurler | 1 | Ranged gargant that also fights well up close. |
| Rock-hurler | 1 | Ranged gargant that also fights well up close. |
Each Rock-hurler is its own unit, so you have three independent models to move around the board. They’re smaller than the giant Mega-Gargants, but they’re still big, tough monsters by anyone else’s standards.
Because Boss-stompers and Rock-hurlers come from the same kit, think about magnets if you want both builds later. The Rock-hurlers are the only version used in the Stone Lobbas Spearhead.
The older Spearhead: Wallsmasher Stomp
Before the 2026 battletome, the Sons of Behemat Spearhead was the Wallsmasher Stomp: three Mancrusher Gargants, one of whom (the Bullstomper) acts as the general. It was sold as Spearhead: Sons of Behemat – Mancrusher Mob, which is simply three Mancrusher Gargants in one box. Its Spearhead rules are still listed alongside the Stone Lobbas, so if you already own three Mancrushers you can keep playing them. The Mancrushers are more of a melee force: they grab enemies, stuff them in their bags and stomp objectives.
If you want lots of Mancrushers for a full army, look out for the new Stomper Tribe box (a Warstomper Mega-Gargant and three Mancrushers), but note that Games Workshop has said it’s only available while stocks last.
The Spearhead Rules
Each Spearhead force has battle traits, a choice of two regiment abilities and four enhancements for your general. Here’s how the Stone Lobbas work, in plain English. For exact wording, check the Spearhead section of the battletome or the free Spearhead downloads on Warhammer Community.
Battle traits
The key rule makes one of your three Rock-hurlers the boss: your general becomes a Hero, which lets him carry an enhancement and use leader abilities. The Stone Lobbas’ other traits reward your shooting. Enemy units you’ve hit with rocks can be knocked about so they struggle to make good charges, and the general can help a nearby gargant aim more carefully.
Regiment abilities (pick one)
- Surly Sorts: once per battle, one of your gargants in combat gets an extra attack with its melee weapons for that turn.
- Greedy and Grabby: all your gargants get a big boost to their objective control.
With only three models, objectives are the hardest part of playing this force. Greedy and Grabby helps fix that, so it’s the best first pick.
Enhancements (pick one for your general)
- ‘Ard ‘Ead: once per battle, your general’s headbutt is more accurate.
- Humongous Strides: your general gets a bonus to his charge rolls.
- Lucky Rock: once per battle, your general throws an extra rock in the shooting phase.
- Hungry Gobbler: if your general kills enemy models in combat, he heals at the end of the turn.
Hungry Gobbler is a great beginner pick. Healing keeps your general fighting, and with only three models, every one matters.
What the Rock-hurlers Do
All three of your units are Rock-hurlers, so the interesting choices come from how you use them together.
Hurlin’ rocks
Rock-hurlers throw rocks at medium range, and the rocks hit hard. Their signature ability, Drop, Toss or Roll, gives each gargant one of three tricks in your shooting phase:
- Drop: they can throw rocks even while they’re in combat.
- Toss: their rocks reach further.
- Roll: their throws are more accurate.
The catch is that each option can only be used by one gargant per turn. So in a typical turn, one Rock-hurler throws from long range, one aims carefully, and one keeps throwing while stuck in a fight. Working out who gets which option is the main puzzle of this army.
In combat
Rock-hurlers aren’t just shooters. They carry massive clubs and can deliver a nasty headbutt, so they can finish off anything that comes close. They won’t out-fight a dedicated melee monster, but they’ll flatten most infantry.
How to Play the Stone Lobbas
Your plan is to soften the enemy with rocks, then step in and finish what’s left, all while keeping enough gargants on objectives to score. You have big, tough models, but only three of them, so you can’t be everywhere at once.
Deployment
Keep the three Rock-hurlers fairly close together. They support each other with the Drop, Toss or Roll options, and the general’s abilities only reach nearby gargants. Use big terrain to hide from enemy shooting on turn one.
Turns 1 and 2
Move to your nearby objectives and start throwing rocks. Use Toss on whichever gargant needs the extra range, and Roll on the one with the most important target. Focus on one enemy unit at a time: destroying units is how you thin out an enemy that outnumbers you.
Turns 3 and 4
By now the enemy will be close. Use Drop on any gargant that’s in combat so it can still throw rocks, and step in with clubs and headbutts to finish weakened units. Keep at least two gargants on objectives, especially if you picked Greedy and Grabby.
Common mistakes
- Splitting up too far. Your gargants work best together. A lone gargant can be swarmed.
- Wasting the Drop, Toss or Roll choices. Plan which gargant takes which option every turn.
- Forgetting objectives. Three models can’t hold four objectives. Pick your battles.
- Charging into the enemy’s best unit. Shoot it first, then charge what’s left.
Building and Painting Notes
With only three models, this is one of the quickest Spearheads to get painted, but each gargant has a lot of skin, cloth and wood. A warm skin tone with a wash and one or two highlights, earthy browns for clothing and leather, and grey stone on the rocks they carry will get you to a great tabletop standard. Spend your extra time on faces and any bits of loot or masonry they carry, which really sell the scale.

Expanding Beyond Spearhead
Your Rock-hurlers are a full unit in Age of Sigmar, and the 2026 battletome gives the Sons more variety than ever. Good next steps:
- A second Boss-stompers box: build them as Boss-stompers for a hard-hitting melee unit to go with your Rock-hurlers.
- A Mega-Gargant: the classic centrepiece. Warstomper, Gatebreaker, Kraken-eater and Beast-smasher are all options.
- Ma Maegran, Chooser of the Mighty: the army’s new caster, who boosts other gargants.
- Mancrusher Gargants: the Stomper Tribe box adds three, plus a Mega-Gargant, while stocks last.

Where to Buy the Box
There’s no dedicated Sons of Behemat Spearhead box: the force comes from one Boss-stompers kit built as Rock-hurlers. It is listed on Amazon US through third-party sellers.

Frequently Asked Questions
Is the Sons of Behemat Spearhead good for beginners?
Yes, especially for painters. Three models is the quickest force in Spearhead to build and paint. On the table, the low model count makes objectives tricky, so it rewards careful planning more than most Spearheads.
Which box do I buy for the Sons of Behemat Spearhead?
One box of Boss-stompers, built as three Rock-hurlers. There isn’t a separate box called “Stone Lobbas”. If you already own three Mancrusher Gargants, you can play the older Wallsmasher Stomp Spearhead instead.
Can I build Boss-stompers and still play Spearhead?
Not for the Stone Lobbas, which only uses Rock-hurlers. If you want both builds, buy two boxes or magnetise the weapons.
What’s in Brawlers of Behemat?
It’s a separate two-player duel game with two Mega-Gargants and terrain, not a Spearhead box. The Mega-Gargants are useful if you want to grow your Sons army, though.
Is the Spearhead box limited?
The Boss-stompers kit hasn’t been described as limited. The Stomper Tribe box of Mancrushers and a Mega-Gargant is a “while stocks last” release, so grab it early if you want it.
How many points are the Stone Lobbas in a full Age of Sigmar army?
Spearhead forces don’t use points, so the Stone Lobbas has no single points cost. If you take your three Rock-hurlers into a normal points game, each unit uses the current Rock-hurler points from the Battle Profiles or the Age of Sigmar app. Points change several times a year, so check there rather than relying on an old list.
Can the Stone Lobbas play against any other Spearhead army?
Yes. Every Spearhead force is designed to be played against any other, so three Rock-hurlers can take on a 20-model infantry force. The low model count means you’ll usually be outnumbered on objectives, which is why picking Greedy and Grabby and keeping your gargants close together matters so much.
