Baleful Regression (spell)

5th-level transmutation
Casting time:	1 action
Range:	60 feet
Components:	V, S, M (a broom or scythe)
Duration:	Concentration, up to 1 minute

You hurl a ball of jet black, vibrating energy at a creature you can see it. Make a ranged spell attack against the target. On a hit, the target must make a Charisma saving throw.
     On a failed save, the target is reduced to an infantile version of itself, or an otherwise inferior form for the duration. Most living creatures are reduced to their infant stage, while unusual creatures like fiends and undead may be reduced to an inferior and smaller but related form. For example, a stalfos might be reduced to a mere stalhead. The creature's equipment is resized, altered, or absorbed as necessary to fit this new form.
     Your DM may decide to use appropriate statistics for the infantile creature if they are readily available. An Ancient Red Dragon affected by this spell could be transformed into a Red Dragon Wyrmling, for example. Otherwise, the following guidelines can be used for the infantile or inferior form:

• The creature has disadvantage on all ability checks and attack rolls.
• The creature is prone, and cannot use its movement to recover from this condition.
• The creature can only speak and understand one of the languages it knows (if any), but can't read or write.
• The creature cannot cast spells, use techniques, or perform other actions which require advanced knowledge and training.

If the target is able to act, it can repeat this saving throw at the start of each of your turns, ending this spell on a success. If the target takes damage, immediately afterward it can repeat the Charisma saving throw and end this spell on a success. If the target is reduced to 0 heart points, the effect of the spell ends immediately, and any excess damage is carried over.
     Any damage or conditions the target sustains in its inferior form are carried over to its normal form.
