So, I'll try my best not to ramble, but this is my first trait uploaded to MTS. I got my inspiration from MamaCallie's Siren trait. Unfortunately it has been reported to have been broken for quite a while. I wanted to simply fix it, however, I'm not the most experienced at modding.

Instead, I decided to revamp their trait, adding some new features I thought of along the way.
Needs

• Sirens' needs are mainly the same, except their social need decays 1.5x faster

Skills and Relationships

• Sirens gain singing skill twice as fast
• Charisma and Mischief are gained about 1.5x faster
• Friendly and romantic relationships are gained around 1.5x faster, and failed romantic interactions don't have as much of a penalty

Misc.

• Sirens have a powerful flirty moodlet by default

Whims

• Kiss A Sim
• Flirt
• Freshen up in a mirror

Depending of which version you download, your siren may also become immortal (Unable to die but can still age) and have a ghostly voice.

Enjoy

Also, as a side note, if anyone has ideas/requests for other custom traits, please comment your ideas!
Update : Hey everyone, I just wanted to state that I'll be taking a short break. So please don't (like anyone would, I'm not that famous of a modder) freak out if i don't post or reply to comments like I've been doing lately. If this mod breaks while I'm on break (Which is highly unlikely considering I don't plan on being gone long) please contact me by PM or commenting! Thanks! 4/20/2017
