Articus's Devolutionary Warrior

Your hand reaches out to touch a humanoid, turning back their evolutionary clock. Their fighting ability increases at the cost of its mind. An unwilling creature must make a Wisdom saving throw. On a failure, the target gains 1d6 Strength, Dexterity, and Constitution (to a maximum of 20), while losing 2d6 Intelligence, Wisdom, and Charisma (to a minimum of 1).

The target has a noticeable increase in body hair if it was not already a furred creature, and other physical features become more primal (such as longer arms or a hunched posture). The targets nails and teeth become sharped and usable as natural weapons (of which the target has proficiency). These weapons deal 1d8 + the targets Strength modifier. If the target already had natural weapons before the spell was cast on them, they now also deal 1d8 damage and gain a +1 bonus to attack and damage rolls. If the creatures intelligence drops below 3, the creature becomes incapable of using any weapons except for their natural weapons.

For an unknown reason, Articus' Devolutionary Warrior does not work on elves. Half-elves gain half as much in Strength, Dexterity, and Constitution, and lose only 1d6 Intelligence, Wisdom, and Charisma, but are otherwise subjected to all other effects of the spell as normal. The spell will fail if cast on construct-based lifeforms, or other races created through non-evolutionary means.
