===Castellan-Class Robot=== 
The Castellan is an assault Robot useful for a wide range of battlefield roles. Its twin power fists and heavy bolter give it a dangerous punch, protected by a power field/synchroniser unit. It can substitute its heavy bolter for a lascannon, melta gun or third power fist, while the standard fists can be replaced with a Siege Hammer, autocannons and flamer.

====Castellax Class Battle-Automata====
[[File:CastellaxBA.jpg|200px|right|thumb|A <s>Castellan</s> <s>Kastelan</s> Castellax robot.]]

In Heresy-era 30k and first to get a Forgeworld model, but for some reason called the '''Castellax''', mounting a [[Mauler Bolt Cannon|Mauler-pattern Bolt Cannon]] on the shoulder which can be replaced with a [[multi-melta]] or a [[Darkfire Cannon]] (essentially a <s>somewhat weaker Lascannon</s> Long Range Plasma Rifle with Lance that blinds enemies that it hits) and coming with a choice of hand weapons.

They are the most common and numerous pattern of Castellans and are designed primarily for siege and shock assault operations. So common, that even the [[Solar Auxilia]] had incorporated them into their army.

Crunch-wise, the Castellax is a surprisingly cheap Monstrous Creature pretty much made to fuck up the Space Marine Legions (thanks to BS4, T7, W4, and armed with AP3 guns base) unless there's list-tailoring involved (like Plasma vets) it'll hold its own against nearly everything thrown at it and can put out a lot of hurt in both the Shooting (thanks to the aforementioned AP3 guns) and Assault, don't let the two Attacks fool you, charging will boost your attacks up to 4 (if you do this make sure to get the Frag Grenades).

Don't let Reactor Blast make you think it's worse to group them up, it's very unlikely to do any wounds to you at all and if you're in assault it'll almost always work in your favor.

If you want them to be [[Choppa|Choppy]], then you may also take dual [[Power weapon#Battle-Automata Power Blade|powerblades.]] At first AP2 rending in melee seems fantastic, but then you remember that this is a monstrous creature; thus it already has AP2 by default via smash. And with S6 its quite likely to be wounding most targets reliably anyway. Unless you absolutely need an extra attack, just stick with stock.

====Castellax-Achea Class Battle-Automata====

The [[Thousand Sons|Nerds]] have their own Castellan pattern and had 'modified' it to suit their psychic needs. How they avoided pissing off the AdMech ''before'' the Heresy is unknown.

Anyways, these Battle-Automata were fitted with a crystalline Psi-control matrix that allowed psychic Space Marines to manipulate them like puppets in a fashion far more seamlessly than standard Legio Cybernetica technology. It is primarily armed with the unique [[Æther-Fire Cannon|Æther-Flame Cannon]].

On tabletop, these <s>Egyptian</s> Prosperine robots are completely different than the mainstay Castellans. For starters, they add Asphyx Shells everywhere with options for a Ætherflame cannon instead of the Mauler. Then they add the Rage and Fearless special rules alongside a special self-destruct that deals d6 S4 AP- hits, like any other Castellax, only differently written. IWND. And the the crown jewel, Psi-Control Matrix is a piece of hardware that might veer a little too Heretek for some people's liking; it allows anyone with at least ML1 to counter the Mindlock that so-hampers Automate from charging, running and making Sweeping Advances, which is by no means terrible, since you can still move and shoot in any target, not the closest one like Automatas with Cortex.

In addition, friendly psykers can draw Line of Sight from any Psi-Control Matrix Castellax for their Malediction and Witchfire powers, but should the psyker suffer Perils the Castellax must pass an LD test as well or take d6 unsaveable wounds, if this kills them their death-splosion has a maxed radius. Achaeas have I4, It Will Not Die, Shred on the Mauler Cannon and beautiful model, all for merely 30 points over regular Castellax, what's not to like? (Hint: they are equipped with twin Power Claw aka Power fist, making em effectively +1A and S10, and priced exactly the same as a castellax equipped with paired blade and wrecker, if it is not enough they don't have Automatic shielding BUT Refractor field, for a sweet 5++ in melee.) Oh, and after all this cheese you won't need Cortex Controller to bring them to the party.

====Kastelan Class Battle-Automata====
[[File:Kastelan.jpg|200px|right|thumb|The Kastelan ready to [[Derp]] on command.]]
In 40k we have the '''Kastelan''' which superficially looks similar to the Castellax, being a somewhat rounded, robotic, monstrous creature type with a shoulder mounted weapon and a pair of [[power fists]] that can be replaced with twin-linked [[Phosphor Blaster]]s, it is also the most common model you'll ever find for 'bots. Though these ones can replace the fists for moar guns. Unlike the 30k version they are less autonomous and operate under "Battle Protocols" which are determined by a specialist tech-priest called Datasmith, but if the priest ever goes missing then the robots just follow the most recent protocol issued to them, [[Derp|which can cause them to stand still and shoot, or to forget they have guns.]]

Apparently, this was done because after the Heresy the Mechanicus came to the conclusion that the Castellax's machine spirit was too close to Abominable Intelligence to be used again. [[Hammer and Bolter]] shows that Tech Priests program them by verbally setting parameters including expenditure authorization, targets, goals and if necessary sacrifice thresholds.

In 8th Edition, Kastelans are improved significantly, as they are far more slot-efficient than the Dunecrawler; getting 6 in a unit. (Spamming them is a trap though, since they're extremely vulnerable in the Fight phase; 2-4 is enough.) They still have the same Monstrous Creature statline, and can reflect guns back at their shooter (for a Mortal Wound now), but are now faster and cheaper.

Fully shooty is actually the cheap option now. Go full phosphor and enter protector mode for 18 S6 AP2 shots per robot. Yes, a full unit of 6 will fire 108 bullets... In protector mode becomes twice as good as any unit we have. Beware combat with this option though, as without the Fists, you don't have any AP in close combat. AdMech now has fewer ways of dealing with high Toughness, and Kastelan Fists in Melee will punch holes in virtually anything, so consider fists if you are lacking in Dunecrawlers. It's recommended if you are going shoot, deck them out with 3 Heavy Phosphor Blasters, or if you are going punchy, get Fists and the Incendine Combustor. Don't mix the Combustor and Phosphor options together, [[FAIL|they don't synergize well.]]

9th edition has been kind to vehicles, and while Kastellans won't benefit as much from ignoring hit roll penalties when moving, being able to shoot in combat means that it'll be extremely difficult to tie them up for long. As you can simply gun down the unit that's tied you up, then focus the rest of the guns elsewhere.
