Sunlight Petrification If exposed to direct sunlight, a cavern troll immediately becomes slowed 1 and can't use reactions or Trample. The slowed value increases by 1 each time the cavern troll ends its turn in sunlight. If the cavern troll's actions are reduced to 0 in this way, they become petrified until they spends at least 1 minute in darkness. Spells like sunburst that create magical sunlight cannot petrify a cavern troll, but the troll is slowed 1 for 1d4 rounds after being exposed to such an effect.
