Iron cobra

Iron cobras were a type of serpentine construct. They were favored by the Scaled Ones for their snakelike form.

Abilities
Iron cobras were, despite their size and metal forms, surprisingly stealthy. Additionally, when ordered by their creator to track down a creature (whose name must be known to the creator), they could detect its position as if by the locate creature spell.

Iron cobras were venomous, with an internal reservoir that held three doses of poison, though said reservoir could be refilled in but a minute. The exact type of poison varied, although venom from a monstrous spider was a common choice.

Combat
Iron cobras' combat tactics were simple, but typically effective: bite until the enemy died.

Ecology
As constructs, they had little to no effect on their surrounding environment, and could be found in any land ecosystem.

Creation
Iron cobras could be created from of iron by a caster of above-average skill who could cast both arcane and divine spells. The creation process also required use of the spells animate object, freedom of movement, geas/quest, and locate creature.

History
It was said that the first eight iron cobras were created ages ago by a powerful wizard-cleric, and that they were indestructible. Other spellcasters after them tried to copy the design, but with uniformly less powerful results.
