Deform

You point your finger at a creature within range and douse the gem in Blood, causing the target to begin deforming and making it look like a grotesque and ungodly creature of indescribable shape.

While you concentrate on this Spell the target has disadvantage on all attack rolls and doesn't have damage resistances or immunities. The target can attempt a Consitution Saving throw as an action and if they succeed they end the effect early but can't act on the same turn.

When this effect ends the target returns to its original form and gains one short-term madness.
