You conjure a deluge of seawater in a 15-foot-radius, 10-foot-tall cylinder centered on a point within range. This water takes the form of a tidal wave, a whirlpool, a waterspout, or another form of your choice. Each creature in the area must succeed on a Strength saving throw against your spell save DC or take 2d8 bludgeoning damage and fall prone. You can choose a number of creatures equal to your spellcasting modifier (minimum of 1) to automatically succeed on this saving throw.
If you are within the spell’s area, as part of the action you use to cast the spell, you can vanish into the deluge and teleport to an unoccupied space that you can see within the spell’s area.
You invoke both death and life upon a 10-foot-radius sphere centered on a point within range. Each creature of your choice in that area must make a Constitution saving throw, taking 2d6 necrotic damage on a failed save, or half as much damage on a successful one. Nonmagical vegetation in that area withers.
In addition, one creature of your choice in that area can spend and roll one of its unspent Hit Dice and regain a number of hit points equal to the roll plus your spellcasting ability modifier.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot above 2nd, and the number of Hit Dice that can be spent and added to the healing roll increases by one for each slot above 2nd.
You create a spectral globe around the head of a willing creature you can see within range. The globe is filled with fresh air that lasts until the spell ends. If the creature has more than one head, the globe of air appears around only one of its heads (which is all the creature needs to avoid suffocation, assuming that all its heads share the same respiratory system).
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can create two additional globes of fresh air for each slot level above 2nd.
