Aegis

Invoke the power of your diety and envelope one creature that you can see within range in a glimmering field of divine energy. The field has hit points equal to 2d8 + your spellcasting modifier. If the target would take damage before the spell ends, the ward blocks that damage and the health of the ward degrades. The ward cannot block psychic damage. If the ward is reduced to 0 hit points, the target takes any remaining damage and the spell ends. Lasts for 1 minute or until destroyed.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the ward hit points increase by 1d8 for each slot level above 1st.
