From Compendium of Worldly Lore
The multiverse is a wonder, and the only prediction one can make is that it is unpredictable. The amazing spontaneity of reality is the foundation upon which chaoticians act. Instead of being tiresome and translucent, the cosmos is marvelous and mysterious. Chaoticians seek to enjoy the beauty of the unpredictable, and by seeking to emulate the philosophy of chaos in their actions, they create a fabulous journey through life in which nothing is ever a bore.
Any character who finds inspiration in disorder is a potential candidate for this prestige class, though members of spellcasting classes are less likely to become chaoticians due to their loss of increased spellcasting ability. Sometimes, chaoticians are discovered lurking in the shadows of a city street, seemingly lost in a confused veil of their own imagination. In fact, they are gazing at the world in its undisguised state: as pure chaos.

Class Features
All of the following are class features of the Chaotician.
Weapon and Armor Proficiency: A Chaotician is proficient with All simple and martial weapons, light, medium, heavy armor and shields (except tower shields)..
Chaotic Contagion Su: A chaotician can attempt to infect a target with chaotic impulses that disrupt the target's ability to defend against the chaotician. If the chaotician makes a successful melee touch attack against the target, the target creature takes a —2 penalty to his Armor Class against attacks made by the chaotician, a -2 penalty on saves made to resist spells or abilities of the chaotician, and a -2 penalty on skill checks opposed by the chaotician. A successful Will save (DC 10 + chaotician's class level + chaotician's Cha modifier) negates the effect and gives the target immunity to similar attacks by that chaotician for 24 hours. This effect lasts for 1 hour per class level.
A chaotician can use this ability a number of times per day equal to his class level.
Scofflaw Su: Divinations cast by lawful characters are difficult to perform on chaoticians. This ability functions much like a nondetection spell, except that it is useful for shielding a chaotician only against creatures of lawful alignment. Such creatures must succeed on a caster level check against a DC of 15 + the chaotician's class level + his Cha bonus (if any) to successfully employ a divination against a chaotician. This ability can be suppressed or resumed as a free action.
Anarchic Grace Su: A 2nd-level chaotician accepts that randomness underlies all reality. Once per day, the chaotician can tap into this randomness to make his movements and posture unpredictable. This effect results in attackers having a 50% miss chance on all their attacks. Even true seeing and similar effects can't offset this ability. Activating the effect is a free action, and it lasts for a number of rounds equal to the chaotician's class level. When it ends, the chaotician becomes fatigued for 1 minute.
At 4th level and higher, a chaotician can use this ability twice per day.
Babble Su: Once per day, chaotician of 3rd level or higher can generate a 10-foot-radius emanation that causes all sounds in the area to turn into garbled, cacophonous, and unintelligible noise. Sounds that issue from, enter, or pass through the area are altered and made unrecognizable as a natural sound. Within this area, verbal communication is impossible. Even something as simple as a shout of surprise is turned into a warped and alien sound. Spells with verbal components cannot be cast. Scrolls and other magic items that require a verbal component to be activated do not function. Spells and items that rely on sound do not function. Sonic damage has no effect.
Clarity of Confusion Su: Starting at 3rd level, a chaotician gains a +2 insight bonus on saves against illusion (pattern) spells, enchantment (compulsion) spells, and spells with the lawful descriptor.
Density's Arbiter Su: A 5th-level chaotician is a friend of chaos and can summon it. Once per day as a free action, the character can either reroll one roll he just made or force another creature to reroll a result the chaotician does not like. A chaotician must use this ability immediately after the result of the roll is known. If he wants to force another creature to reroll a result, the chaotician must be able to see the other creature, and it must be within 60 feet of the chaotician. Whether rerolling his own roll or forcing another to reroll, the results of the second roll stand.
