Silken Line

Anchor a strong thread to a point, creature, or object within range. For the duration, you can climb, swing, pull yourself 20 ft., lower a creature safely, or pull an unattended object of up to 100 pounds up to 20 ft. as a bonus action.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
