Change species

This spell attempts to force a creature into a new shape, forcing a shapechanger's power to truly change their form onto another against their body and soul's will. You cannot try to transform a creature into a race whose basic CR is higher than the level or CR of the creature being targeted.

The caster must make a melee spell attack against a living creature, on a hit the creature must make a special constitution save where they add the difference between their own constitution modifier and the creature the caster is trying to transform them into, in addition to the difference between the targetted creature’s proficiency modifier and the proficiency modifier of the creature the caster is trying to transform the target into.

On a fail the target is transformed for the duration, they take on all physical characteristics of the creature, however, any differences between their race’s default ability scores and their own is applied to their new form, though it cannot increase ability scores above 20 unless the core were already above 20 without this feature, nor can it reduce any mental ability scores to below 1.

On a fail the target must also make a wisdom save, on a success they retain their normal mental faculties for the duration, on a fail they have the mental statistics of the creature they were transformed into.

While the creature is transformed their health is reduced by 1 for every size category they go down and every value their constitution modifier is reduced, and is increased by 1 for every size category and increase in their constitution modifier they gain for the duration. The creature also loses the ability to perform any action their new form would be unable to, such as holding a weapon if they have paws. The creature retains their personality and memories, however they also gain the species they are transformed into’s instincts and if they failed their wisdom save they cannot perform any action that would require one of their mental ability scores to be higher then their new stats.

If the spell is reversed any effects you had while in your new form transfers over, if you had less then your maximum health your health at the time you transform equals health when transformed back / maximum health of your new form * the maximum health of your original form.
