Virtue

You touch one creature, imbuing it with vitality. If the target has at least 1 hit point, it gains a number of temporary hit points equal to 1d4 + your spellcasting ability modifier. The temporary hit points are lost when the spell ends.

At Higher Levels. The spell's temporary hit points increase by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
