Dragon's Elemental Legion

This spell allows you to call forth a small army of elemental creatures, each infused with the power of a dragon. When you cast Dragon's Elemental Legion, choose three types of elemental creatures from the following list: air, earth, fire, or water.

You summon a total of twelve elemental creatures, with four of each type you chose. These creatures appear in unoccupied spaces within range and remain for the duration or until they are reduced to 0 hit points.

Each elemental creature is infused with the power of a dragon, granting them additional strength and abilities. They have an additional 20 hit points and deal an extra 2d8 damage with their attacks. The elemental creatures also gain immunity to the damage type associated with their element (air: lightning, earth: bludgeoning, fire: fire, water: cold).

Additionally, each elemental creature within 60 feet of you gains the ability to breathe a 30-foot line of elemental energy associated with their type once per turn. Each creature in the line must make a Dexterity saving throw, taking 8d6 damage of the associated type on a failed save, or half as much damage on a successful one.

The creatures are friendly to you and your companions, and they obey your verbal commands. You can use your action to issue commands to all elemental creatures you summoned, telling them what to do on their next turn.

When you cast this spell using a spell slot of 8th level or higher, you summon an additional four elemental creatures for each additional level of the spell slot.
