Alatreon's Aegis

You harness the elemental power of Alatreon, creating a shifting 15 foot radius aura of ever-changing energy. For the duration, you can use a bonus action on your turn to switch between four different elemental aspects, each with its own effect:

1. Inferno Aspect: Creatures within the radius take 4d8 fire damage, and a creature that starts its turn in the aura takes 1d8 fire damage.

2. Frost Aspect: Creatures within the radius take 4d8 cold damage, and their speed is reduced by 15 feet until the start of your next turn.

3. Thunder Aspect: Creatures within the radius take 4d8 thunder damage, and they must succeed on a Constitution saving throw or be dazed for a minute. A dazed creature can only take an action or bonus action during their turn and can't concentrate on spells. They can remake this saving throw at the end of their turn, ending the effect on a success.

4. Dragon Aspect: Creatures within the radius take 4d8 force damage, and they must succeed a constitution saving throw or have their elemental resistances negated for 1 minute. They can repeat this saving throw at the end of their turns, ending this effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage for each aspect increases by 1d8 for each slot level above 5th.
