School: Chronomancy (Enchantment)
(Intended for use with the Chronomancer subclass)
Duration: 1d10 + 5 days
When this spell is cast, the affected creature loses all sense of time. It is perpetually late, unable to function under any time restraints. This spell is merely an annoyance unless accurate timing is crucial. Creatures afflicted by this spell automatically lose initiative and are always surprised if attacked from stealth. In combat, creatures with multiple Actions automatically lose one Action, and Bonus Actions and Reactions cannot be used. A Wisdom save negates the spell.
Against another spellcaster, or a creature of the demiplane of time, this spell is particularly effective. Any spellcaster under the effects of the Temporal Disjunction who attempts to cast a time-affecting spell automatically fails. Any native creature of the demiplane of time also loses any time-related abilities, and suffers 2d6 + 1 point per caster level points of damage. In both cases, any ability (natural or spell effect) to slip between reality and the demiplane of time is lost. Chronomancers and creatures native to the demiplane of time gain a +1 to their Wisdom save against this spell.
The Time Dimielemental is the hardest hit by the Temporal Disjunction: In addition to the above penalties, it also loses its ability to slip in more copies of itself.
Based on the 2e AD&D spell of the same name, from the Chronomancer suppliment (TSR 9506).
