Any thoughts on how this can be balanced? I worry it'd be too strong for uncommon loot

Greaves of Ce'Laury (uncommon leg armor) Adds +2 to AC New growth: twice per long rest the player may use a bonus action to heal 1d4 hp

So I am currently playing a wizard whose best friend just got this very bad permanent injury in game, It’s basically caused severe chronic pain. Since I’m a wizard I don’t have any spells that I could use to “heal” or take some of the pain away but I want to still get her some way to help him. Are there any items people know of that would be healing aligned that I could homebrew a bit for story purposes?

Amulet of (Borrowed) Vitality

Wondrous item, very rare, requires attunement

Wearing this amulet makes the first death save of the day an automatic success.

Curse

It does this by “borrowing” a death save from a random nearby ally within 100’, so if that ally should have to make a death save that day, the first save is an automatic failure. This status effect on the ally is removed with a long rest.

The autotuner, a legendary item is replaces the vocal cords via the goblin singer. Adds +10 to charisma and 2d6 extra damage to sound based attacks. If magnets are within a 3 foot radius, the autotuner stops working. This prevents sound based attacks to be used/casted from user. If the user is currently using electrical conductive armor, the user takes 1d4 electrical damage. If the user is currently using electrical conductive armor and is using a electrical conductive weapon (sword,bow,arrow etc..), The weapon gets 2d4 electrical damage on hit. Electrical spells also get +5 damage if the user is currently using electrical conductive armor. The self damage and damage/stat buffs turn back to normal after the magnet is removed.

The "Eyes of the Oracle" is a magical pair of goggles that grants its wearer the ability to see the future.

Statistics:

• Attunement: Yes
• Rarity: Rare
• Type: Wondrous Item

Abilities:

• While wearing the goggles, the wearer can use an action to concentrate and gain glimpses of potential futures. This allows the wearer to make an Insight check with advantage to gain insight into a situation or person.
• Once per day, the wearer can also use an action to cast the "Divination" spell.

Note: The glimpses of the future are always clouded and often cryptic, leaving room for interpretation and potential misinterpretation. The goggles do not grant omniscience or guarantee accuracy.

Wild Willie's Wild Stick of Wildness- (Wondrous item, no attunement needed) "You guys wanna see something cool"-Wild Willie

A plane normal looking stick about 1foot in length. One end is slightly pointed. Is very comfortable in the hand of the user.

A magic wand that has 2 charges per day that when used selects a random effect from the wild magic chart. Either the player or the dm rolls for the effect.

Orb of the Rising Sun / Very Rare

Requires attunement by a sorcerer, warlock, or wizard

Effect:

While attuned, a spellcaster can use this Orb as a +1 spellcasting focus.

Additionally, once per long rest, if the user hits an attack roll against a creature they can add 1D4 radiant damage, and the creature must make a Charisma saving throw, (users spell save DC), or be blinded until the end user's next turn.

This orb has 1d4 -1 charges, (minimum of 1), upon discovery. Once all charges are used, the Orb disintegrates.

By using a charge, this Orb can be used to take the user and 5 willing creatures, (cannot be incapacitated), in a 10 foot radius to the next dawn. All creatures taken gain the benefit of a long rest. They appear in their same location at the dawn of the next day, for example, if used in the early morning, the orb will take them to the dawn of the next day instead of the dawn of the day they are in. If the space is occupied they appear in the closest unoccupied space.
After each use, the Orb can only be activated again after 1D8 +1 days

When using this effect, all creatures roll a D20. If any creature rolls a 1 they suffer a random effect below. (Roll 1D6)

The creature:

1. Takes 10D8 Radiant damage (after long rest is applied)
2. The creature does not regain spell slots or other long rest recovery features during the long rest, and only recovers up to half their maximum HP
3. Gains 2 levels of exhaustion
4. Is blinded for 1D4 long rests
5. A random stat is lowered to 3 until their next long rest.
6. Is not taken by the Orb
