Cripple

One creature of your choice within range has their speed reduced to 0. For 10 rounds, their speed stays at 0, they can't benefit from any bonus to their speed, and nothing can end this effect. After 10 rounds have passed, the target's speed remains at 0, and any bonuses to their speed they receive only last for 1 round. A greater restoration or wish spell cast on the target can end this effect after 10 rounds have passed, but nothing else can. Once the effect ends because of one of these spells, the target suffers 2 levels of exhaustion. If the target reaches 6 levels of exhaustion, if they are revived, this spell restarts from the beginning as if it was just cast, except 10 rounds is 10 hours, and 1 round is 15 minutes.
