Conjure Living Spell

You call for the might of your patron. You conjure a living spell of a CR of 5 that fills a 10-foot cube within range. The spell can be chosen from any spell list.

The spell is conjured in the following way:

Damage Immunity. Replace the living spell’s damage immunity with immunity to the type (or types) of damage dealt by the chosen spell.

Magical Strike. Replace the damage that Magical Strike deals with one type of damage dealt by the chosen spell.

Spell Mimicry. Replace the effect of Spell Mimicry with the effect of the chosen spell. If that spell requires a saving throw, use spell save DC from the replaced spell, and if the spell involves an attack roll, use the attack bonus from the living spell’s Magical Strike.

For example, if you turn fireball (a 3rd-level spell) into a living spell, customize the living lightning bolt. The living fireball has immunity to fire damage, instead of lightning damage; deals fire damage with its Magical Strike; and replicates fireball with Spell Mimicry.

The Living Spell is friendly to you and your companions for the duration. Roll initiative for the Living Spell, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the elemental, it defends itself from hostile creatures but otherwise takes no actions.

If your concentration is broken, the Living Spell doesn't disappear. Instead, you lose control of the Living Spell, it becomes hostile toward you and your companions, and it might attack. An uncontrolled Living Spell can't be dismissed by you, and it disappears 1 hour after you summoned it.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the challenge rating increases by 1 for each slot level above 5th.
