You infuse a creature with dark magical energy. It must make a Wisdom saving throw. On a failed save, the energy nestles in the core of the creature’s soul until the end of your next turn. At this time it blossoms into negative energy, driving the creature mad with rage and hatred. The creature loses its ability to feel empathy and is plagued by dark thoughts to harm others. Its alignment becomes chaotic evil.
For 1 minute, the creature will enter a blind rage and attack friend and foe alike, focusing its most deadly attacks on allies first, before diverting its attention to foes. The creature has no concept of what it is doing during this minute, only that inflicting pain and death brings it pleasure.
At the end of the minute, the creature will regain awareness and knows exactly what it did during the rage. The rage can be ended early by dispel evil and good or telempathic projection augmented to impose serenity.
