This spell is a weaker version of the 7th-level wizard spell limited wish. Alter occurrence enables the wizard to alter the way an event in the very recent past actually occurred. For the casting of the spell, the wizard recounts an event which occurred up to two rounds previous which he viewed firsthand. The wizard, while recounting the incident, modifies it in the way which he would have liked for it to occur. At the end of the casting, the past will be rewoven along the lines of the wizard's version, by a base guideline of 3% per level of the wizard.
For instance, Johann, a 12th-level wizard, uses the spell to make a freak gust of wind blow an arrow totally off course which shot his companion Rykor in the heart a few seconds ago - a critical hit. Johann has a 36% chance to make the arrow miss, else it still hits doing regular damage. If Johann had asked for the arrow to have missed Rykor's heart, it might have still hit Rykor but would have done only 100-36 = 64% of the designated damage.
This spell will automatically modify the perceptions of the past for all of those, other than the wizard, who were present during both the modified and unmodified events unless they make a saving throw versus spell. Alter occurrence cannot be used to raise character abilities (even temporarily) or mimic other magical effects. Frequent use of this spell may cause the wizard to go insane; make an Intelligence check with a cumulative -1 penalty each time the spell is used by the same wizard over a one week period, or suffer a random type of insanity.
Alter occurrence is a spell published by the wizard Saridan Hysakai after over a decade of study, an unknown amount of which was spent at the plane of time. Saridan subsequently went insane.
