Homebrew:Daiklave of Conquest

Weapon (longsword), rare (requires attunement)

As an action, you can cause any creatures of your choice within 30 ft. to make a Charisma saving throw. Each creature that fails the save becomes frightened of you for 1 minute. Whether they succeed or fail, they suffer disadvantage on the next saving throw they make before the end of your next turn. All creatures within 30 ft. of you (including yourself) who you did not subject to a saving throw get +1 on their next attack roll before the start of your next turn, and are immune to frightened until the start of your next turn.

This daiklave has 3 hearthstone sockets instead of the normal 1.
