Blue Blizzard: Diamond Heart

You clutch the petals tightly in your hands and wish upon the Poinsettia's grace. As if heeding your pleas, you and your allies are swirled by petals of various blues, and your bodies are enveloped in a shimmering aura.

When the spell is cast, all allies within a 20ft. Emanation of you will regain 3d6 Hit Points and Temporary Hit Points plus your spellcasting ability modifier. Until the spell ends, a Bloodied ally who starts their turn within the Emanation will restore half of the healing amount. This effect repeats at the start of your turn, using the newer roll, until the spell ends.

Additionally, when an ally in the Emanation is reduced to 0 Hit Points, they will be reduced to 1 Hit Point instead. Every ally can receive this effect only once per casting of the spell.

If an enemy starts their turn within the Emanation or enters it on their turn, they must succeed in a WIS. saving throw or be Charmed until the start of your next turn. While Charmed in this way, the enemy must move away from you and end its turn. Taking damage while Charmed in this way will not end its effects on the enemy. On a successful save, a creature is immune to being Charmed by this spell until it is cast again.

Using a Higher-Level Spell Slot. The healing and Temporary Hit Points increase by 1d6 for each spell slot level above 3, and the maximum duration of the spell extends by 1 round. When cast at 7th-level or higher, its healing instead increases by 2d6 for each spell slot level.
