This spell creates a ray of glowing light that leaps from the caster's fingertips to a distance of 80 yards. Only the first creature touched by the ray is affected, and it can avoid the ray by making a successful saving throw vs. spell at a penalty of -3.
An affected creature exactly repeats the actions it took in the preceding round. Thus, if it took two steps forward and one step left in the previous round, it would take two steps forward and one step left in the current round. The repeated actions are carried out even if they force the affected creature into an obstacle, over a cliff, or into a chasm.
The ray of Ondovir ruins any attacks or spellcasting that the target creature begins in the same round that the ray strikes. If the creature struck by the ray had spent the previous round readying weapons, it spends this round doing so, too; if it fought with weapons, it duplicates its previous movements exactly—thus a mobile opponent can avoid the creature's attacks and strike it with relative ease—the creature's Armor Class is worsened by 4 for the round.
If the affected creature cast a spell on the previous round, an attempt to cast the same spell must be made in the current round. If a second identical spell has not been memorized, no spell effect occurs (even if a second spell is available, it will be cast in the exact location as the first).
When the round of helpless repetition caused by the ray of Ondovir is complete, the creature is instantly released from all control.
Notes: Very rare spell from the Forgotten Realms setting. Known to be in the Tome of Rathdaen.
