Engorge Gastropoda

You magically enhance a snail or slug that you can see within reach, which rapidly swells in size and takes the form of a Haungharassk (DotMM). It appears in an unoccupied space that you can see within range. The gastropod returns to its original form when it drops to 0 hit points or when the spell ends.

The gastropod is friendly to you and your companions for the duration. Roll initiative for the creature, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the gastropod, it defends itself from hostile creatures but otherwise takes no actions.

At Higher Levels. When you cast this spell with a spell slot of 3rd level or higher, your snail can take the form of a Smollusk. With a spell slot of 4th level or higher, your snail can take the form of a Flail Snail (VGtM, 144).
