With Corruption and Rot I cast your body into decay.
The spell speeds up a target’s count from dead status to dissipation. Once the target’s count reaches 3 minutes, they must dissipate.
Once cast the person’s count is reset at 2 minutes. This must be lower than the time they had left in their count such that if an individual had only 30 seconds left the spell would not alter the count but would still force the dissipation once the count reached 3 minutes.
