Barnaby's Armor of Poison Immunity, Studded Leather

You have immunity to Poison damage while you wear this armor.

Grappling Hook: your armor has a built in grappling hook with a 30 ft range. Make a ranged attack against a target. If the attack hits, the type of target determines the next outcome:

If the target is a structure or a creature of size Huge or larger, you can pull yourself through the air to the target.

If the target is a creature of size Large or smaller, you can attempt to pull the creature up to 10 feet closer to you. Both the target and you must make competing Athletics Checks. The target moves 10 ft toward you if the target loses the contested check and then, at the end of your turn, the grappling hook shoots back to your armor.

Healing Word: your armor grants you the ability to cast Healing Word at 3rd level (6d4) once per short rest. 

Legendary Resistance: Once per long rest, your armor grants you the ability to use a legendary resistance as a reaction when you fail a saving throw, turning it into a success instead.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
