Components: V, S

Range: Close (25 ft. + 5 ft./2 levels)
Target: One living creature
Duration: 1 day/level (D)

Spell Resistance: Yes
Description
You infect the target’s mind with a crippling distortion of self-perception, causing them to dramatically overestimate their competence while simultaneously eroding their actual understanding. The subject becomes supremely confident in their abilities - especially where they are least capable.
Effects
Upon failing its saving throw, the target selects (or the caster designates) one Knowledge skill, Profession, Craft, or any one skill in which the target has fewer than 5 ranks. This becomes the affected domain.
The target suffers the following effects:
- Takes a –6 penalty on all checks with the affected skill.
- Gains a +4 morale bonus on Bluff, Intimidate, and Diplomacy checks when asserting competence in that skill.
- May attempt untrained checks with the affected skill even if normally prohibited.
Cognitive Distortion
The target is convinced of their expertise and cannot willingly accept that they are mistaken:
- The target automatically believes they succeeded on any failed check involving the affected skill unless the failure has immediate, undeniable consequences (DM’s discretion).
- Any creature attempting to correct or advise the target must succeed on a Diplomacy check opposed by the target’s Bluff check or be dismissed as ignorant.
Escalation (Overconfidence Spiral)
Each time the target fails a check with the affected skill, they must make a secondary Will save:
- Failure: The penalty increases by –2 (cumulative, maximum –10), and the morale bonus increases by +1 (maximum +6).
- Success: No change.
Moment of Doubt (Suppression Clause)
If the target is confronted with overwhelming, undeniable failure (such as catastrophic consequences directly tied to the skill), they may attempt a new Will save with a +4 bonus:
- Success: The spell is suppressed for 1 hour.
- Failure: The target instead rationalizes the failure, immediately triggering the Escalation effect.
Special
- Creatures with 5 or more ranks in the affected skill gain a +2 bonus on their initial saving throw.
- Creatures with 0 ranks in the affected skill take a –2 penalty on the save.
- If cast on a creature already suffering penalties to Wisdom, increase the spell DC by +1.
Material Component (Optional Flavor)
A fragment of chalk or a scrap of poorly written notes, crushed during casting.
Lore
Though now regarded as a malicious enchantment, Dunning–Kruger Invocation is widely believed to have originated in the lecture halls of The Fraternity of the Veiled Quill, an order of mages devoted to the study of knowledge, rhetoric, and intellectual humility. Early records suggest the spell was first developed as a pedagogical tool - a controlled means of demonstrating the dangers of overconfidence to novice apprentices. By allowing students to experience the illusion of mastery firsthand, instructors hoped to instill a deeper respect for disciplined study and self-awareness.
The spell is most commonly attributed to the rival arcanists Archmage Dunning and Magister Kruger, whose infamous collaboration has become the subject of academic legend. Dunning, a meticulous theoretician, was obsessed with the limits of mortal cognition, while Kruger was a sharp-tongued lecturer known for publicly humiliating overconfident students. Together, they devised the enchantment after a series of increasingly bitter disputes with apprentices who believed themselves more knowledgeable than their masters. Ironically, surviving correspondence suggests that each wizard believed the other to be the lesser intellect - leading some historians to speculate that the spell’s creation may itself have been influenced by its own principle.
Over time, the spell escaped its academic origins. Rival scholars began using it in debates, subtly unraveling their opponents’ credibility by causing them to speak with unwarranted certainty on subjects they poorly understood. In political courts and noble salons, the spell found new life as a weapon of social sabotage - courtiers enchanted with it would confidently offer disastrous advice, misinterpret critical information, or undermine their own authority before key audiences. Entire careers have been quietly ended under its influence, with victims rarely understanding what went wrong.
Among experienced arcanists, the spell is both feared and grudgingly respected. It serves as a reminder that ignorance alone is rarely dangerous - it is the illusion of competence that leads to catastrophe. Some masters still employ a moderated version of the enchantment in advanced training, forcing students to confront the limits of their understanding. Yet even they warn that repeated exposure carries risks, as the mind can grow accustomed to its own false certainties. In rare cases, those subjected to the spell too often begin to exhibit its effects even in the absence of magic - a condition some grimly refer to as “true enlightenment’s shadow.”
