You have an uncanny ability to utilize the elemental forces of water. You gain the following benefits-

• You gain a swimming speed equal to your walking speed and can breathe underwater.
• Your dexterity increases by 1 to a maximum of 20.
• Once every long rest you can call upon a mephit to assist you. The mephit appears within 30 feet of you as a bonus action. The mephit is an Ice mephit, a mud mephit or a steam mephit. Regardless of its type the mephit is friendly to you and obeys your commands. It disperses if you summon a new mephit.
