Alrighty then. Xaver is about to become a merman, with associated abilities and such to go along with it. He's gonna get pulled out to sea and be turned into a merman by a NPC character while out there. Gonna be unconscious for a few days, then wake up with it having already been done while he was unconscious.
Species change from human to merman.
Merman Physique - Instead of having legs, Xavier instead has a fish tail, starting from his waist downwards. He's able to move completely fluidly in the water, and is able to swim at speeds similar to that of bottlenose dolphins. While underwater, he has a natural resistance to the cold and can swim comfortably underwater in cooler temperatures, however water colder than the average temperature around the island will affect Xavier like a regular human. Getting out of the water will make Xavier's body affected by the cold like a regular human.
Underwater Breathing - Xavier is able to breath underwater.
Water Requirement - If Xavier is out on the land for a consecutive 6 hours, his body will rapidly start to dry up. He will rapidly experience signs of extreme dehydration which will find that the consumption of liquid doesn't get rid of the issue. Leaving it alone can and will result in Xavier’s own death. In order to get rid of the issue, Xavier must submerge his body entirely in water to 'reset' this timer. Submerging himself in fresh water, or water like in swimming pools and/or tap water will only give Xavier 3 hours before he has to submerge himself again. Staying in water will keep the timer reset, and it only starts being relevant again once he is out of water. Regardless of if he is in water or not, if he is using a human shape charm, the timer will be active.
