Torvald's Bad Gnus

Summon a herd of 1d4+2 spectral gnus. Each spectral gnu chooses an enemy at random within a 30 ft square centered on the caster and charges at it. Treat this as a magical attack on any enemy creatures in range. On a hit, each target takes 1d8+2 bludgeoning damage. More than one gnu may target a single enemy if there are more gnus than enemies in range. Additionally, any enemy creatures in range must make a DEX saving throw or be knocked prone. Once a gnu has struck a target it disappears.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the bludgeoning damage increases by 1d8 for each slot level above 2nd.

The mighty Torvalds never forgave the gnus for what they did, and thus imbued them with his rage.
