I’ve been playing some Pathfinder Adventure Card Game and my favorite item is my minor healing wand. It doesn’t heal much, but its clutch when you need it. Let’s make that in DnD 5e
Wand of Minor Healing
Wand, rare (requires attunement by a spellcaster)
While holding this wand, as an action you cast a minor healing spell healing the character hit points equal to 1/2 their level (minimum 1). The wand then must recharged for one hour until it can be used again.
