Rare and Magic Items (by R0bobot)

I've been making a couple items in my spare time, and I thought I'd share them here. Apologies in advance because this is my first time using homebrewery. All feedback is appreciated.

Gauntlets of Grazing

Item (Gauntlets), Uncommon

When identified, it is revealed to be an enchanted set of gauntlets designed to help focus and hone the aiming of its user.

When wielding a melee or ranged weapon, if the user's attack role is equal to, or one less than a target's AC, the user does 1/2 damage, rounded down.

Wrath and Ascension

Weapon(Unique, One Handed), Very Rare

A portable weapon of advanced design, "Wrath and Ascension" is a powerful, expensive siege weapon. It is, for all intents and porposes; a portable, pointed battering ram affixed to a gauntlet. It excells in boring holes into walls, generating great structural damage. This feature has proven itself useful in battle against heavily armored opponents. Unfortunately, the mechanics of the device make it incredibly rare, if not almost nonexistent on the battlefield.

"Wrath and Ascension" does a base 1d8 piercing damage and can be used in two different modes. It does double damage against all structures.

Standby Mode: 5 ft reach; can activate the weapon, the pointed head shoots forward, dealing an additional 2d6 piercing damage; Once the head is fired, it automatically resets to standby position, "Wrath and Ascension" can only be activated 3 times per long rest.

Lance Mode: 10 ft reach; can be moved into this position as a bonus action; "Wrath and Ascension" cannot be activated in this mode.

Repentance

Weapon(Rapier)/(Longsword), Rare (requires Attunment)

An odd weapon from years long past, "Repentance" is a thrusting sword with a serrated edge near the hilt. To any normal individual, the blade seems wierd, if nothing special. However, once wielded by an individual with a guilty soul, "Repentance" reveals itself.

In order to activate the sword's magical properties, a guilty individual must inflict 1d6 damage to themselves using the sword. Once done, the blood coating the blade alters in form, solidfying and temporarily changing the weapon to a curved longsword.

This changes the sword's damage die to 2d6 + (self inflicted damage roll) for 1 minute, and can be used once per day.
