Carmens Metamorphosis

You endow yourself with monstrous resilience and prowess fuelled by your patrons magic. Until the spell ends, you can’t cast levelled spells, and you gain the following benefits:

• You gain 50 temporary hit points. If any of these remain when the spell ends, they are lost.
• Whilst you possess temporary hit points you have resistance to all damage except psychic.
• You grow to large size.
• You gain a +2 to your AC.
• Your eldritch blast cantrip becomes a melee spell attack using your charisma modifier to attack, rather than a ranged spell attack, and creatures that are hit with this attack take an additional 2d12 acid damage.
• You have proficiency in Strength and Constitution saving throws.

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
