Reverse Engineering the spells "False Life" and "Wither and Bloom", gives range to "False Life" as if it were "Healing Word".

Bolstering someone within 60 feet with a necromantic facsimile of life, they gain 1d4 + 4 temporary hit points for the duration.  The caster drinks the alcoholic beverage and the false healing goes to the recipient.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you gain 5 additional temporary hit points for each slot level above 1st.

Because it's harder for arcane casters to cast healing spells, the spell is second level and the caster takes 1hp of damage per level of spell slot the spell is cast (so minimun 2 hp)
