I really enjoy the merfolk, and they work in Sulani. They swim as fast as jet skis with max fitness, they are great for diving for treasure, seashells, spearfishing, and taking underwater photos. The ability to change the weather and influence moodlets are nice too. The can cause rain, sunshine, and thunderstorms. Their siren song can cause the flirty, inspired, tense, and sad moodlets. They can summon an ocean threat and lure sims into the sea to try and drown them (they never drown though). They can summon an Azure Dolphin. They have the mermaid kiss that helps prevent other sims from drowning.
The biggest problem with them is the lack of an underwater lot to explore and the dried scales moodlet that glitches. I would love a level system that can unlock new abilities. Currently, Seasons has monsoons, blizzards, and heatwaves. It would be nice if merfolk could influence stronger weather, change the temperature, sing songs that cause more moodlets like anger, focused, and happy, or they could summon more things from the sea.
The different tiers could be:
Siren Charmer
This would be abilities centered around the siren lullaby's and other musical abilities. Maybe a sim will get a passive boost to music skills, especially singing. You could also make the siren song impossible to ignore (Believe it or not, the siren lullaby does not always work). With all the ways to avoid death, it would be interesting if your sim could sing a special song that can charm the reaper and prevent death.
Weather Master
It could involve summoning stronger weather and even granting immunity to weather that normally requires satisfaction points. With eco-living, making the weather windy or sunny could impact energy generation and your bills. Windy weather is also ideal conditions for building the fitness skill. Certain weather conditions are needed to complete certain tasks for aspirations. The length of time weather is present after changing it could be affected.
Ocean Manipulator
This could be focused on summoning ocean threats, befriending different sea creatures like dolphins, and it could even have an impact on the ability to catch fish. A passive boost could be not feeling sad about catching fish. After all, bigger fish always eat smaller fish in the ocean.
Being good and evil also impacts what merfolk can do, so it would be nice if the abilities in the tier were influenced in a similar way. It could be like how your reputation impacts your celebrity perks.
Aside from that, I haven't had enough time to play with other occults, but I think it would be nice to include more occults and make some edits to existing occults.
Merfolk are an occult people will never see in their game if they don't awaken the household to them. I think many occults behave in a similar way. Normal sims can live their realistic lives without encounters with many occult sims thanks to how they hide themselves from those who don't go looking for them. I do like the idea of magic hiding in plain sight.
