Mechalik
Mechaliks are enormous clockwork spiders, made of bronze and gold and with razors on the ends of their legs and in their mouths. Mechaliks are made for many different purposes, to guard, to hunt or to attack. They obey their masters unflinchingly, and they emit a loud screech when they attack. Some claim that there is a recipe for a much larger and more powerful Mechalik somewhere in existence, one with en exoskeleton of unbreakable platinum.

Razor Slash: If a Mechalik attacks one creature with all of its claw attacks and its bite, the razors on these appendages start to move and chop, and each attack deals an additional 1d4.
Breath Weapon: A line of acid dealing 16d10 damage, reflex save DC 25 for half.
Globe of Invulnerability: As the spell, this effect is permanent and centered on the Mechalik. The globe had a 15ft diameter, large enough to cover the Mechalik at its longest point.
Screech: As a standard action, a Mechalik can emit a loud screech. All creatures that hear this must make a will save DC 25 or suffer a -4 to all attacks and saves for as long as they can see the Mechalik. A creature that makes this save is immune to this Mechalik’s screech for 24 hours.
Repair: If a Mechalik spends an entire round repairing itself, it heals 10d6 damage.
