Homebrew
You create a shimmering protective barrier around a creature of your choice within range. The ward grants the creature temporary hit points equal to 5 + your spellcasting ability modifier. While the ward is active, the creature has advantage on saving throws against being frightened.
At the start of each of the creature’s turns, the ward absorbs 2 damage from any source. When the temporary hit points are depleted, the ward ends.
When you cast this spell using a spell slot of 2nd level or higher, the temporary hit points increase by 5 for each slot level above 1st.
