Determinism
Tier 1 Epic abjuration
Casting Time: 1 action
Range: 120 feet
Components: V, S, M (a diamond from a parallel universe)
Duration: 1 minute
You curse a creature you are aware of within range, altering its fate to determine its future actions. When the target attempts to take its action on each of its turns, it must offer you an alternative action that it is able to take that cannot be the same type of action as the first (Attack action, cast a spell, Dodge action, etc.). You select which action the creature must take between the two options presented. The creature need not tell you what it will do with these actions or how they work, only that it wishes to take them.
At the end of each of its turns, the creature may attempt a Wisdom saving throw to end the effect. If the creature succeeds on two Wisdom saving throws in this manner, the spell ends.
At Higher Levels. When you cast this spell as a tier 3 Epic spell, you increase the number of successful Wisdom saving throws the creature must make to end the spell by one, to a total of three.
