Custodians of Fiduciary Duty

The Bank Inviolable makes a nice juicy target - the only bank in the only civilized city in all the land.  Why hasn't it been robbed?  Well, this is why:

Custodian of Fiduciary Duty
No. Enc: 1d4 (1d4)
Alignment: Neutral
Movement: 150' (50')
Armor Class: -2
Hit Dice: 12
Attacks: 2
Damage: 5d8 or 6d6
Save: F1
Morale: 12
Hoard Class: See below

The Custodians are the massive guardians of the Bank Inviolable.  They are man-shaped robots, 20’ tall, of iron and gold.

Embedded in each arm is a minigun  and a rocket launcher.  A Custodian has 10,000 rounds stored in its abdomen to feed the minigun, and a burst from the gun does 5d8 points of damage.   Alternatively, the Custodian may fire a rocket from its arm, doing 6d6 points of damage to all within 30’ of the target (save vs. spell for half damage).  Custodians only carry 4 rockets, however.  The miniguns have a range of 200’, and rockets may be fired up to 1000’ away.

This robot has searchlights built into its head to illuminate dark areas and blind a selected opponent (as if a light spell was cast upon it, save vs. spells to look away or be blinded for 1d10 rounds).  This blinding can occur simultaneously with the rocket and/or minigun attacks.  The robot’s eyes are sensitive to light across the ultraviolet and infrared spectrums, and it is additionally capable of using echolocation to detect opponents.  Unless these capabilities are suppressed, it is impossible to surprise one of these machines.

Each Custodian is equipped with a cooling system that causes it to take half damage from fire-based attacks (and no damage on a successful save).  This mitigates the risk of explosions from the ammunition stored in their abdomens.  This causes them to be more susceptible to cold-based damage, and a Custodian will take an extra point per die of cold damage.

A Custodian is only partially susceptible to mind-affecting spells, due to its three independent electronic minds.  Each mind “votes” on every action independently, and the body will act upon the decision of the majority.

If destroyed, 10,000 gp worth of gold may be recovered from the Custodian’s body.
