Web Sense. While in contact with a web, the spider knows the exact location of any other creature in contact with the same web.

Time Skitter (Recharge 5–6). As a bonus action, the spider momentarily blurs through fractured time, teleporting up to 30 feet to an unoccupied space it can see. Opportunity attacks against it have disadvantage until the start of its next turn.

Fate Predator. When a creature within 30 ft. rerolls a die (such as from advantage, Lucky, Portent, etc.), the spider can use its reaction to deal 10 (3d6) psychic damage to that creature.
