Circle of the World-Serpent

You pull on the essence of the world serpent that is destined to crush the world once it is released. A force of nature that is unstoppable even in the efforts of a god.

Creature of the Ocean

At 2nd level the World-Serpents essence has granted the ability to take the form of a creature that has a trait that allows it to breathe underwater as long as it has a CR rating equal to your Level+Wisdom modifier. However if the creatures CR rating is higher than your Level you will find yourself under an effect of lethargy, once you drop the wild shape you must make a constitution saving throw(DC 10) and on a failure you gain a level of exhaustion but if you succeed the DC for your next transformation increases by 5.

Watery Grave

At 6th level you gain the ability to wrap water around those you defeat using cold damage, acid damage or a spell that manipulates water which grants them disadvantage on death saves until they are stabilised and if they die from the damage or from death save fails you gain temporary hit points equal to your Wisdom Modifier doubled.

King of the Sea

At 10th level you are granted immunity to any effects caused by water for example if you were in water you do not suffer negatives from difficult terrain and if you were to succeed on a dexterity saving throw and you would take half damage you take none and if you fail the saving throw you take half.
