# Hellfire Engine >[!rimg]+ > ![[Placeholder2.png]] *This automaton thunders forward, its metal plates shrieking with each step, looking like an armored giant. Through the gaps at its joints you can see the white-hot light of some inferno raging within. Its head is terrifying, wrought to appear like a bearded man with the horns of a stag, its mouth opened impossibly wide.* <div class="grid-container"><div class="MON">Hellfire Engine</div> <div class="CR">CR 19 (204,800 XP)</div> <div class="SOU">Fiendish Codex 2 pg. 119</div> <div class="SYS">Dungeons & Dragons 3.5</div></div> N Huge Construct **Init** -1 **Senses** darkvision 60 ft., low-light vision; **Perception** +0 #### defense **AC** 37, 7 touch, 38 flat-footed (-1 Dex, +30 natural, -2 size) **hp** 282 (44d10+40) **Fort** +14, **Refl** +13, **Will** +14 **Feint** —, **Demoralize** — **DR** 15/adamantine and good **Immune** construct traits, fire; **Resists** acid 10, electricity 10, sonic 10 **Weakness** vulnerable to cold #### offense **Speed** 20 ft. **Melee** 2 slams +52 (1d8+10 plus 6d6 hellfire) **Space** 15 ft., **Reach** 15 ft. **Special Attacks** breath weapon (60-ft. cone, 20d10 hellfire, DC 32 half), death throes, hellish heat (6d6 hellfire) #### statistics **Str** 30, **Dex** 8, **Con** —, **Int** —, **Wis** 11, **Cha** 1 **BAB** +44, **CMB** +56, **CMD** 65, **TA** +52, **RTA** +41 **Skills** Perception +0 #### special abilities ### Breath Weapon (Su) Once every 1d4+1 rounds, a hellfire engine can exhale a 60-foot cone of hellfire. Creatures in the area of effect take 20d10 hellfire damage. A successful DC 32 Reflex save halves the damage. The save DC is Constitution-based. ### Cold Iron Attacks (Ex) A hellfire engine is constructed entirely out of cold iron. Its slam attacks count as cold iron for the purpose of overcoming damage reduction. ### Death Throes (Ex) A hellfire engine explodes when it is destroyed. All creatures within 60 feet of the engine take 20d10 points of damage (DC 32 Reflex for half). The save DC is Constitution-based. ### Hellish Heat (Su) A hellfire engine radiates such an intense heat its mere touch deals additional hellfire damage. Hellfire is similar to fire, but not subject to fire resistance or immunity, and does full damage to objects. #### tactics A hellfire engine responds to the simple commands of its creator, just like a golem, although it can also be ordered to follow the commands of another creature. When ordered to fight, it opens up with its breath weapon and then ambles forward, its fists leaving fiery arcs in the air. A hellfire engine’s most notable trait is the pure hellfire it spits at its opponents. No creature in the known cosmos can resist a hellfire engine’s awful attacks. Many devils speculate that hellfire engines serve not only to annihilate legions of devils, but also to deter any of the dukes of Cania from turning against Mephistopheles. #### ecology **Terrain** Any land (Hell) **Organization** Solitary **Treasure** None **Advancement** 45–48 HD (Huge); 49–98 HD (Gargantuan) Hellfire engines are infernal constructs constructed as artillery for use in the Blood War. Hellfire engines are tools of war. They anchor armies, lending impressive artillery to the ranks of devils. When not on loan to stem the fl ood of demon invaders, these constructs serve their creator, Mephistopheles, acting as guards or even just symbols of the devil’s power and prestige. Hellfire engines are native to the Nine Hells of Baator, but they can be found in any land or underground. A hellfire engine stands 16 feet tall and weighs 40,000 pounds. ### Construction A hellfire engine is assembled from 40,000 pounds of cold iron bathed in the blood of a dozen celestials and then polished with a rare blend of brimstone, sulfur, and acids found only in Hell, costing at least 80,000 gp. Assembling the body requires a DC 20 Craft (armorsmithing) check or a DC 20 Craft (weaponsmithing) check.
