You transform yourself into a twisted aberrant mass of flesh and raw power, brutally effective in its capabilities but horrifying to behold. For 1 minute, you gain the following benefits:

• Your size increases by 1 category.
• Your AC becomes 20, if it is not already higher.
• You are resistant to all damage.
• You have blindsight up to 30 feet.
• At the start of your turn, all creatures within 15 feet of you must make a Wisdom saving throw or become frightened of you until the start of your next turn. If a creature succeeds, it’s immune to this effect for 1 minute.
• As an action, you can make three melee spell attacks with a reach of 10 feet using your ever-shifting eldritch appendages. Each attack deals 1d10 + your spellcasting modifier damage on a hit, or 3d10 + your spellcasting modifier if the target is frightened of you. These attacks deal any damage type of your choice.

If you lose concentration on this spell, you remain transformed for the rest of the 1 minute duration, but give into the violent urges of your form. You must spend each of your turns either attacking a creature or moving towards a creature by the fastest available route with the intent to attack it. If there are enemies you can see, you can choose to pursue attacking one of them. If there are no living enemies you can see, you must attack a randomly determined ally. At the end of each turn, you can choose to make a Wisdom saving throw against your own spell save DC to end the transformation early.
