Tomes of Bludgeoning

You create magical tomes that fly at a creature or target that you can see within range. That creature or target must succeed on a DEX saving throw or take 2d6 + [your Spellcasting modifier] bludgeoning damage.

If a creature rolls a nat 1 on the DEX save, chaotic forces emerge from the magical tomes, dealing an additional 2d4 chaos energy damage. (Roll on the d8 chart from Chaos Bolt to determine damage type.)

At Higher Levels. When you cast this spell at higher levels, you create an additional 2 tomes per spell level, dealing an additional 2d6 bludgeoning damage. Any chaotic energy damage also increases by 2d4 per level.
