A dwarvish siege weapon from Kelvin's Cairn.
Siege engine was a term for an expansive variety of weaponry, machines, and temporary structures that were designed for the purpose of siege warfare.[1][2][3][4]
Weaponology[]
Siege engines were typically used in offenses against walled cities or fortified towns, castles, or other kinds of fortresses.[4] Because of this they were rare to non-existent in areas of Toril that lacked such structures, such as Chult.[5] Beyond land, weaponry derived from siege engines were mounted on ships and used in naval combat.[6][7] And beyond Toril itself, many spelljammers utilized weapons that were derived from siege engines.[8]
Those skilled in the building and maintenance of siege engines were known as siege engineers.[3][9][10][11][12] It was common for them to supervise the operation of siege engines.[12] Soldiers primarily skilled in their operation were known by some as artillerists.[13]
Siege Engines in the Realms[]
Bombardment Engines[]

From left to right, clockwise: a ballista, a scorpion, a trebuchet, and a mangonel.
Bombardment engine was a term for any siege engine that was designed to hurl large missiles.[14][15] Some had little to no accuracy, firing their projectiles indirectly high into the air, and thus had to be pointed in general directions rather than at specific targets.[15] While others fired in low, flat curves, and thus were more accurate.[16]
- Ballista: A stationary form of siege weapon that resembled an oversized crossbow,[3] mounted on a swivel.[17] They typically fired heavy, spear-like missiles,[1][17] though could be made to fire round shots of metal or stone. Of the bombardment engines they were fairly accurate and had a trajectory that was relatively flat.[17]
- Bombard: A large pipe of wrought iron or bronze that shot large, but relatively light weight, stone balls[14][17] or cast iron "cannonballs" in a high arch.[14][17][18] They could be found in wildspace, though only rarely due to often being impractical compared to ballistas or catapults.[18] They could also be found used on ships on Toril, being one of the largest weapons on the planet to require smokepowder charges.[19] However, they were quite rare, expensive, and dangerous to use.[20] Even more rare were the Thayan bombards, a distinct magical form of bombard that was developed by the Red Wizards of Thay.[21][22]
- Catapult: A massive variety of siege engine,[14][3] usually consisting of a lever made from a flexible material mounted on a sturdy frame.[15] They were capable of hurling rocks and other heavy objects high into the air at long distances, deriving this power from tension.[14][3][15][23] They could be further separated into heavy and light catapults, which were different in size and had different limits to what they could hurl.[14][3][15]
- Goblin hucker: A trebuchet-like device that was developed by hobgoblins. Rather than a traditional platform, these were designed to be worn upon the back and shoulders of ogres by means of an elaborate leather harness that took around 10 minutes to attach. Though designed specifically for use by ogres, they could theoretically be worn by any similarly large creature. Goblin huckers were also designed with the intent of hurling goblins as missiles, typically adorned with a spiked helmet, though they could just as easily launch similarly sized projectiles like rocks or flaming casks of pitch.[24]

The great crossbow of DaRoni.
- Great crossbow: A siege engine resembling a gigantic crossbow, far larger than a ballista, that was developed by the gnome inventor Nadul DaRoni. Originally developed for King Azoun Obarskyr IV, copies of the invention were later sold within Aurora's Whole Realms Catalogue.[25]
- Hurler: A simple rock throwing siege engine developed by Nadul DaRoni that was far smaller in size than similar engines, like the catapult and mangonel.[26]
- Mangonel: Another torsion powered siege engine, related to and often confused with the catapult.[23]
- Scorpion: A bolt throwing siege engine similar to, but lighter than, ballistae.[27][28] They were roughly the size of a light mangonel and used an intricate system of pulleys, running along both sides of their base, to provide torsion power comparable to that of a heavy mangonel.[29] Scorpions were once used in the late 15th century DR by the forces of Baron Krelas Ugarak to defend the Molten Vault.[28]
- Trebuchet: A massive variety of siege engine similar to catapults. They relied upon gravity and the potential energy of their heavy missile loads, a lever and counterpoise system, to fire from great distances.[1][14][15]
Crushing Engines[]

A bore and a battering ram.
Crushing engines were siege engines that were designed to breach gates or walls through various means, such as impact, but did not utilize missiles.[30]
- Battering ram
- A battering ram engine or "suspended ram" consisted of a heavy, sturdy pole that was supported by and suspended within a wheeled gallery,[3][30][29][31] either by ropes[29] or chains that were slung around the scaffolding's roof beams.[30] This allowed its crew to swing the ram back and forth against objects with ease, requiring less energy than battering rams that weren't suspended in a frame.[3][30] These poles were also often capped with a heavy, reinforced metal head.[30][31]
- Bore
- also known as a sow, was a siege engine designed for use against stonework. They were similar in design to a suspended battering ram,[1][30][31] consisting of a wheeled gallery with a central mechanism (usually a log), capped with a large metal screw bit, that was suspended from its roof beams with slings. This manner of suspension allowed the mechanism to turn about its axis. It was operated by pulling back the mechanism and letting it swing into the target, much like a wheeled battering ram. Some bores instead had stakes of metal or wood driven into the mechanism along their length, which acted as handles for operators to manually rotate it against the target.[30] The weight of bores varied from 100‒600 lb (45‒270 kg).[32]
Miscellaneous[]
- Arcane: a variety of magical siege engines in the 15th century DR that were used by Thay,[33] based defensively around the Thayan Plateau, and by the floating Netherese citadel Kolthunral.[34] They were designed to hurl various type of arcane energy, such as fire, force, and lightning.[33]
- Flame cannon: A siege engine that was designed to hurl casks of alchemist's fire.[35]
- Greek fire projector: A metal tube that was designed to fire everburning oil.[36]
- Siege tower: Massive mobile wooden towers.[1][3][32] They were typically built as a beam frame standing 30‒40 ft (9.1‒12 m) tall , with a ladder on its back or interior,[1][32] with wheels or atop rollers.[3] Some were built with drawbridges and a partially enclosed deck at their top.[1][32] They were designed to be moved up against an enemy structure and allow troops to scale over while under the cover of the tower.[3]
Notable Siege Engines[note 1][]
- Kezefbane, a magical siege engine that was used by the Knights of Samular to turn the tide of the Second Troll War.[37]
Notable Users of Siege Engines[note 1][]
Groups[]
- Both members of the City Guard and Navy of Waterdeep had many members skilled in siege engineering.[9]
- The Company of Hunnar was a mercenary company that specialized in siege warfare and utilized a wide variety of siege engines.[38]
Nations & Settlements[]
- The Citadel of the Respected had three massive siege engines stationed atop its towers that were capable of hurling small boulders against any ship that threatened the city of Muluk.[39]
- The Citadel of the Raven housed many great siege engines within its armory, which were used to slay two out of three dragons that attacked the citadel in the month of Eleasis, 1356 DR.[40]
- Cormyr.[41]
- Upon the cliffs overlooking Port Llast were siege engines capable of hurling boulders.[42][43]
- The kingdom of Scardale notably had siege engines in Harborwatch Keep in defense against pirates.[44]
- The walled Thayan city of Surthay had siege engines within many of its towers.[45]
- The nation of Turmish and its capital city of Alaghôn had siege engines in their standing army, which their founder Dempster Turmish chose not to utilize when besieging the walled city of Hlondeth in 145 DR.[46]
