It’s Madness Week, and while you may be expecting some Lovecraftian monstrosity, you’re not going to find one, because that’s what they want us to do. Instead, I’ve got another kind of sanity-eroding monster for you: the reality-warping insanitrix.
This creature appears to be a faceless humanoid, but its body is made of a shimmering, silvery metal that seems to roil and ripple, as energy pulses arc off its body in tiny bursts.

SQ warp reality
Annihilation (Su): A creature struck by an insanitrix’s annihilation bolt must succeed on a Fortitude saving throw (DC 32) or suffer 20d6 points of damage. A creature reduced to 0 hit points in this way is utterly annihilated, as the spell disintegrate. The saving throw DC is Charisma-based.
Imaginary Shield (Su): An insanitrix gains a deflection bonus to AC equal to its Charisma modifier.
Maddening Aura (Su): All insanitrixes are insane, and their madness is highly contagious. Each creature that begins its turn within 120 feet of an insanitrix must succeed on a DC 32 Will save or suffer 1d3 points of Wisdom drain. For every 5 points of Wisdom drain a creature suffers in this fashion, he gains a permanent madness, either chosen by the GM or determined at random. The saving throw DC for madnesses gained in this way is 32, rather than the normal DC. The saving throw DC is Charisma-based.
Prismatic Touch (Su): A creature touched by an insanitrix’s prismatic touch is affected as though by prismatic spray, suffering an effect from one of the spell’s colors chosen at random. The saving throw DC is Charisma-based.
Warp Reality (Su): As a standard action, an insanitrix can alter the laws of physics in a 60-foot radius centered on itself. It may choose a single effect to implement within this radius, which moves with the insanitrix. The effect lasts for 1 minute. The insanitrix can potentially choose virtually any effect, but GMs should use the following as guidelines:
With great and cosmic power such as that wielded by the most powerful of arcane spellcasters, one must either be very wise, to handle that power safely and fairly without unforeseen repercussions, or else one may become maddened by one’s own power, driven to heights of hubris that cause them to ascend from being petty mortals to become something entirely new. Insanitrixes are incredibly powerful spellcasters who have half-ascended to a semi-divine status, driven irreversibly insane by the experience.
Many scholars believe that each insanitrix holds within it the seeds of some new plane of existence or even multiverse, and that they subconsciously are attempting to overwrite our current reality with their own version of it, their very presence causing the rules of this universe to warp and twist as it struggles to take hold.
