Your spell bolsters your allies with storybook plot armor. Choose a creature within range and visible. The target's hit point maximum and current hit points increase by 1d8 + your spellcasting ability modifier. When a creature hit with a melee attack or touch spell effect the shield does damage equal to the temporary hit points lost to the damage. The damage is fire or ice damage selected when the spell is cast. The spell ends if the temporary hit points are depleted or after 8 hours, whichever happens first.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the targets temporary hit points gained and hit point maximum increase by an additional 1d8 for each slot level above 1st.
