Survival in New Vance

Bonus Action. You fire a high-tensile grapple line at a climbable surface or a Large or smaller creature within 60 feet. If targeting a surface, you can pull yourself up to 30 feet. If targeting a creature, it must succeed on a Strength saving throw or be grappled, reducing its speed to 0. You can use a bonus action to pull yourself 15 feet closer to the creature, and the grapple lasts until you release it or the creature breaks free with a successful check.
