Enlightened Polymorph

This spell transforms a friendly beast or monstrosity that you can see within range into the humanoid of your race.

The transformation lasts for the duration. The target's game statistics, excluding physical ability scores, are increased by half of the casters mental ability scores. It retains its alignment and personality.

The target assumes the hit points of half the caster. When it reverts to its normal form, the creature returns to the number of hit points it had before it transformed. If it's knocked to 0 hit points while transformed, the creature dies. The creature is limited in the actions it can perform by the nature of its new form, and it can't speak(unless it already knew a language) or cast spells(unless it already knew them). The memories from its time as a humanoid may be simplified when it Intelligence reverts.

The target can be given equipment in this form, but it up to the DM if they know how to use it.
