Tortoise
Tortoises are armored levitating vehicles. A tortoise consists of a shell in the shape of a trapezoidal box. A hoverpod under each corner of the shell supports its weight. The shell is large enough for two draft animals, such as anathaks to fit inside, along with a crew-served weapon such as a spellcannon. The shell has a hatch in front, a second hatch on top, and a door in back. The front hatch provides its weapon with a line of fire, the top hatch allows its crew to survey its surroundings, while the back door provides access to the interior of the vehicle as well as an escape route if the vehicle is threatened with destruction. The vehicle moves by driving the draft animals inside it, and driving them differentially allows the vehicle to rotate.

Tortoises are commonly covered in field stabilized earthworks. The reason for this is that it allows the tortoise to be lightweight when it is being transported to the battlefield, but heavily armored when it is actually in battle. In addition, if the soil used in the field stabilized earthworks are dug up with vegetation still attached, this vegetation serves as a form of camouflage, allowing the tortoise to blend into its surroundings and be mistaken for a terrain feature.
The main purpose of the tortoise is to protect weapon crews against sniper fire. Without this protection, a powerful spellcannon could be neutralized by an infantryman with a ray crossbow. Because of the presence of line-of-sight ray weapons on the battlefield, no artillery piece can reliably outrange small arms, so protecting weapon crews is a high priority. Of course, a solidly constructed tortoise with field stabilized earthworks can take quite a bit more punishment than just a few force bolts. Tortoises can withstand power arrow attacks, as well as attacks from enemy spellcannon. In a firefight, tortoises can go toe-to-toe against turret golems and are often the last thing standing in battle.
The main drawback of the tortoise is that it is slow, especially on uneven terrain. This puts it at a tactical disadvantage against turret golems, which can often outflank them. More importantly, a tortoise has a very difficult time not being overrun by enemy infantry. On the other hand, tortoises are relatively inexpensive to build, and are easier to transport into battle than iron golems.
