Zergling (3.5e Monster)

Zergling
Slow regeneration: Zerglings regain 1 hit point per hour, and can regenerate one lost limb per eight hours of rest.

Two claws: Zerglings can use both claw attacks during any standard attack, charge, or full attack action.

Strategies and Tactics
There are a couple of common Zergling tactics. Small numbers of them may harry undefended targets. Large groups of them may sweep through bases, killing everything. They may also simply lie in wait for their enemies before popping out of their hiding places to begin the slaughter.

For Players
Players can take the Zergling as their familiar if they have the Improved Familiar feat.

A basic (unupgraded) Zergling requires a caster level of 5 to serve as an Improved Familiar. For every 3 caster levels above 5, you may use a Zergling with 1 CR worth of additional upgrades.
