Wondrous Item, Rare (Requires Attunement)
This bracer houses a deadly blade, perfect for trapping prey. While you are attuned to two of these blades at the same time, they count as a single item for the purposes of attunement.
Armed and Dangerous. As a bonus action, you can extend or retract the blade housed within this bracer. While the blade is extended, you gain the following benefits:
Your unarmed strikes gain 5 feet of reach, and you can have them deal Slashing damage instead.
You can make a grapple check even if you do not have a free hand, using the extended blade instead. A creature grappled by the extended blade takes 1d6 Slashing damage when it uses its action to escape the grapple.
Whenever you hit a creature with an opportunity attack, that creature’s speed becomes 0 for the remainder of that turn.
Beware its terrible sickles, for there is no escape from their clutches.
