Veil of Flesh

Choose up to three skeleton under your control within range. Your spell grows a coat of flesh and skin over the skeleton, granting it 2d8 + spellcasting ability modifier temporary hit points and making it appear physically identical to the creature(s) used for this spell's material component(s) to the unaware eye for as long as it has these temporary hit points. Additionally, the skeleton is no longer vulnerable to bludgeoning damage as long as it has these temporary hit points.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target two more skeletons for each slot level above 5th. Using a spell slot of 7th level or higher makes the duration of the spell permanent until the temporary hit points are lost.
