Transmogify Animal

You infuse up to twelve beasts within range, with magic transforming it into a beast of CR 2 or lower, permanently. The beasts can only transform into another beast of similar species (ie. A cat can transform into a tiger, a dog into a dire wolf, etc). If the beast wishes to resist the transformation they must make a Charisma saving throw against the caster's spellcasting DC. If they are willing, no save is required. If successfully transformed the beasts will be charmed by the caster for the next minute. Afterward, they will regress into whatever instincts they had before being transformed and either turn hostile or abandon you.

You may make a Wisdom (Animal Handling) check with a DC set by your DM to keep the transformed animal as an ally. If the animal was already your pet then you gain advantage on this check. This spell cannot be used on an animal companion, familiar or summoned creature.

At Higher Levels. When you cast this spell using higher-level spell slots you may increase the CR of the creature it is to be transformed into by one level per slot above 5th (ie. When used at 6th level this can create a CR 3 beast).
