Evolutions
The person has 3 simple bolas, they deal DEX HP in damage. They use them to immobilize their adversaries. It works on any medium-sized creature or smaller, with a penalty of 1 to attack. A STR or DEX check, Difficulty 10, is required to break free, but it takes one turn. Otherwise, one must be made every turn, until release, with -1 to the difficulty per turn.
The person now has a normal bola, it no longer has a penalty to attack, it deals 1d4+DEX damage, and always has a range of 30m. They can craft 5 bolas, using a twenty-meter rope, stones, and two Dexterity checks at Difficulty 10 for each. The rope is not reusable.
The mountaineer has a bonus of 3 to catch without dealing damage, against certain animals and monsters (alpine animals, ibex, chamois, wolf, eagles, stone giant, bear, snake, lycanthropes, vampire, and bats...). The bonus is 1 for all other creatures. A DEX check at Difficulty 15 is required to break free, then -1 each turn.
The mountaineer now deals 1d6 damage, thanks to a spiked bola of their own design (DEX check, Difficulty 15, to turn a bola into a spiked bola).
