You create a magical connection between yourself and one willing creature that you touch. Once connected, if either creature falls or would take damage from a trap or area of effect (but not attack rolls from a creature), the other can use its reaction to pull the creature 10 feet toward it before the target takes damage or falls. If this movement moves the target within 5 feet of the other, it can grapple the creature as part of the same reaction so long as it has one free hand.   The spell ends once used in this way, if you or the target cast this spell again, move more than 30 feet away from one another, or are separated by full cover.
