Tuthken - Desert Humanoid Nomads, Scavengers, Raiders and sometimes Reluctant Heroes

This is my take on the Tusken Raiders found in the desert parts of my fantasy world. Not cruel, just hungry and desperate that are well know for their attacking anyone that approaches "their territory." They can make temporary allies, if the other group keeps their word and has something the Tuthken need. In the desert, they are a constant threat, in the pyramids, they maintain a delicate treaty to ensure things are better left undisturbed.

This can happen only once every round, regardless of how many Tuthken surround or attack their victim. This increases to +2d6 at 6HD and +3d6 at 10HD.

Tuthken are powerful and despotic desert raiders who prey on any other travelers that are smaller in numbers that they believe they can defeat. Similar to humans in appearance, but they cover themselves in grey or sand-colored rags both to conceal themselves and protect themselves from the harsh desert winds. Their body is covered by brutally horrid scars that occasionally erupt in pus if exposed to extreme heat. If they start to suffer, they are helpless for long periods to their infections, it is their hands and faces that continually breakout. For the few who reach higher age and skills, they become immune (Desert Adaption at 6 HD)

They have a strong clan type of organization that welcomes any singular Tuth, but those who join are treated terribly until they prove themselves. Any adult male can be sent out on hunting expeditions that has only one rule - do not come back empty handed. While they use keen tactics to hunt fearsome beasts, they sometimes must rely on raiding towns or caravans to ensure they are not punished or shamed by their clansmen.

They have multiple tactics that they reuse such as rigging a bridge, or stalking a road with pits, they time their attacks when victims will be most disadvantaged. Tuthken are smart enough to scavenge anything that falls into their clutches, often sold again to other raiders, they sometimes make exceptions for weapons or magic. They are often seen trailing caravans, and many experienced desert folk attack these raiders on sight.

When they make contracts they keep their promises. In most instances they are extremely favorable for them. If they believe the other side is not keeping their word, will look for a chance for revenge at an opportune time.

While many stories tell of their dark appetites, fortunately these are mostly jube-tails, told to inspire fear. They attack for profit and slaves are not their preferred spoils; usually they prefer to end fights by letting individuals flee. These nomads never enter the Phastian pyramids scattered throughout the desert except in dangerous times when they have no other option. Their tales tell of horrible monstrosities that if disturbed would bring misery to the world.
