Boon Of Cybernetics

(Disclaimer: This is not a feat, this is a boon. Only a DM can give this boon to their players) 

You've replaced a good chunk of your body with advanced machinery. 

 - Increase your Strength score by 2, to a maximum of 20.

- You gain proficiency with unarmed strikes as long as they're done with the cybernetic limb, the damage die is a d8. 

- You gain a climbing speed equal to your walking speed.

- Your cybernetic limb acts as a grappling hook, letting you make a ranged weapon attack as a bonus action towards an creature, object, or wall. This grappling hook has a range of 30 feet will do 1d6 + dexterity piercing damage on hit.  You can choose to either go towards the target or try to bring the target towards you. If the target resists, then they need to make a  strength save against your strength check.
