Desert Monsters from the City of Spires

A few monsters who have turned up in my current campaign. I think my PCs have figured all these guys out well enough for me to safely list them here.

Smoke Giant: AC chain, 4 HD, 2 fists (1d8 damage), morale N/A.

Smoke giants are artificial guardians created by a long-fallen civilisation. In their dormant state, they just look like a thick covering of soot, coating everything in the room they guard. When they are disturbed, however, the soot flies up into the air and rapidly coheres into an ogre-sized humanoid monster, jet-black from head to foot. The giant furiously attacks anything that enters its protected area. If reduced to less than half HP, or if the trespassers depart, it explodes apart into a cloud of choking black smoke, which gradually settles to the ground as thick black soot. In smoke/soot form it recovers 1 HP per round until fully healed, at which point it will cohere back into humanoid form if the trespassers are still present. If reduced to 0 HP it explodes into smoke and does not recohere. 

If a dormant smoke giant can be collected into a container while in soot form without triggering it, then the resulting container can be used as a missile weapon: the moment it is opened, the giant will explode out of it to attack anyone nearby. Smoke giants are sometimes found still lying dormant inside their original storage crates.

(Once my PCs worked these guys out, they dealt with them by building an improvised suction pump attached to a hose, which they used to suck up the soot a little at a time from outside the giant's trigger radius. Then they mixed the soot with clay and baked it into bricks, effectively imprisoning the giant. The smoke giant's attempts to reform itself from inside the bricks makes them vibrate violently whenever anyone approaches, allowing them to function as an intruder alarm system.)

Locust Spirits: AC chain + shield, 4 HD, 1 claw (1d8 damage + strength drain), morale 8.

These awful famine-spirits look like shadowy humanoid locusts. They are only semi-corporeal and take half damage from non-magical attacks. Anyone struck by their claws is filled with terrible weakness, as though they hadn't eaten for days, and loses 1d6 strength - this strength returns at the rate of one point for each decent meal they eat. Anyone falling to Strength 0 is reduced to an emaciated corpse, apparently the victim of months of starvation. 

Locust spirits are only semi-intelligent, and can usually be found as servitors to more powerful spirits or dark magicians.

Jackal Knights: AC plate, 6 HD, 1 greatsword (3d6 damage) or 1 bite (1d6 damage), morale 9. 

These terrible demon-warriors of the desert can take the form either of a jackal (in which case they have a bite attack, and can run much more swiftly than a human), an armoured jackal-headed warrior (in which case they have a greatsword attack, and move at human speed), or a dust devil (in which case they have no attacks, but are immune to non-magical attacks, can move at much greater than human speed, and can blow through narrow spaces). Shifting between forms takes one round. 

In jackal or warrior form, they have long, lashing razor-sharp tongues, with which they can attempt to open the arteries of one opponent per round in melee combat. Unless their target is wearing armour on their neck, wrists, and thighs, they must save each round or else be cut, bleeding out for 1d6 damage per round. Spending a full round bandaging the wound allows for a new save to stop the damage. Any healing magic stops the bleeding instantly.

Jackal Knights register as magical to Detect Magic, and casting Dispel Magic on a Jackal Knight in dust-devil form will force it to resume one of its corporeal forms.

Desert Zombies: AC leather, 2 HD, 1 claw (1d6 damage), morale N/A.

This one was adapted from a Pathfinder monster. Created from the dehydrated corpses of unfortunates who perished in the wastes, these zombies resemble dried-out desert mummies aside from the candle-like flames that flicker inside their hollow eye-sockets. By day they slumber beneath the desert sands, quiescent unless disturbed, but by night they wander the in search of prey, their eye-flames visible from afar off in the darkness of the desert night. If they hit anyone in melee, their target must save or be grabbed and pulled in close enough for the zombie to exhale its dessicating breath all over its victim, causing an additional 1d8 damage in spontaneous dehydration. 

The flames in their eye-sockets serve as their eyes: immersion in sand cannot extinguish them, but immersion in water can. A zombie whose eye-flames are extinguished is effectively blind, and will simply wander randomly. If it is still animate by the following dawn, the flames in its eye-sockets reignite the moment the sun comes over the horizon.
