Druid

You conjure a Large, intangible spirit from the Elemental Planes that appears in an unoccupied space within range. Choose the spirit’s element, which determines its damage type: air (Lightning), earth (Thunder), fire (Fire), or water (Cold). The spirit lasts for the duration.

Whenever a creature you can see enters the spirit’s space or starts its turn within 5 feet of the spirit, you can force that creature to make a Dexterity saving throw if the spirit has no creature Restrained. On failed save, the target takes 8d8 damage of the spirit’s type, and the target has the Restrained condition until the spell ends. At the start of each of its turns, the Restrained target repeats the save. On a failed save, the target takes 4d8 damage of the spirit’s type. On a successful save, the target isn’t Restrained by the spirit.

Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 5.

Your touch inflicts a magical contagion. The target must succeed on a Constitution saving throw or take 11d8 Necrotic damage and have the Poisoned condition. Also, choose one ability when you cast the spell. While Poisoned, the target has Disadvantage on saving throws made with the chosen ability.

The target must repeat the saving throw at the end of each of its turns until it gets three successes or failures. If the target succeeds on three of these saves, the spell ends on the target. If the target fails three of the saves, the spell lasts for 7 days on it.

Whenever the Poisoned target receives an effect that would end the Poisoned condition, the target must succeed on a Constitution saving throw, or the Poisoned condition doesn’t end on it.
