Aquatic Refuge

You conjure an interplanar refuge that merges the comforts of "Magnificent Mansion" with the tranquility of water. When you cast this spell, you create a magnificent mansion infused with the essence of water, providing an alternate version of "Magnificent Mansion" with the following variations:

1. Appearance: The mansion's exterior transforms into a beautiful aquatic structure, appearing like a grand underwater palace, complete with flowing water columns and shimmering seaweed.

1. Special Features: The mansion's interior retains the luxurious amenities from the original spell. However, water-themed elements permeate each room, with gentle waves, bubbling fountains, and a refreshing mist filling the air. The atmosphere is cool and comfortable, offering a soothing experience.

1. Guardian Nymphs: Upon summoning the mansion, you have the power to call upon two water nymphs or a single water elemental to serve as guardians within Aquatic Refuge. These loyal protectors assist you and your allies, defending the mansion throughout the spell's duration.

1. Healing Waters: Any creature within the mansion's confines benefits from an accelerated healing effect. At the start of each of their turns, they regain hit points equal to their Constitution modifier multiplied by the spell's level (minimum 1), as long as they have at least 1 hit point.

1. Watery Sanctuary: Once per day, you can cast a water-themed spell of 5th level or lower as a bonus action, within the confines of the mansion, without expending a spell slot. This feature can only be used once during the spell's duration.

1. Nautical Escape: If the mansion is threatened or you choose to end the spell early, the mansion transforms into a swirling pool of water. Any creatures or objects within it are safely transported to the nearest body of water, up to a mile away, as long as a substantial water source is available.
