Wartomancy

"Sorry kiddo!  Face my mighty Wartomancy!!!"  *cackles in toad.*  - The Wizard King.

You touch a creature you can see within range and they must make an Intelligence saving throw.  On a failed save, the creature is Toadified! for 10 minutes.  This save can be performed at the end of each of the affected creature's turns.

Toadified!: if a creature was Toadified!, they must have been the subject of a curse or enchantment that turned them into a massive Toad (about 5 feet tall, which is pretty tall for a toad).  As a Toad, they lose all actions they could perform (other than moving, I guess) and gain a tongue attack (which is gonna hurt for around 1d8 bashing damage plus however strong they are).  Toads are pretty good at jumping too, so if the afflicted creature were to attempt to jump somewhere, they jump 1d100 feet.  Completely unrelated to the Toad's jump, a Toad also weighs around 250 pounds.

*if this spell is cast by The Wizard King or his lich, the spell turns the target creature into a tiny Toad, which has none of the above abilities and has the frog stat block.

**the afflicted creature's hit points do not change, regardless if this spell is cast by The Wizard King.
