Breathe of the Dragon

The power of dragons flows through you and grants you access to their most impressive ability. Choose a dragon species from the table below. For the duration of the effect, you are resistant to the specified damage type. Also, you can use an action to exhale destructive power. The dragon species you choose determines the area of effect and the damage type, from which you inflict 4d6 points to all creatures in the area of effect that fail a saving throw. A successful saving throw halves the damage. Once you have used this action, roll a d6 at the beginning of each turn for the duration of the effect. Only on a 5 or 6 can you use the Odem weapon again.

At higher Levels: If you cast this spell with a spell slot of 5th or higher degree, the damage increases by 2d6 for each degree above 4th, up to a maximum on 10d6.
