Enigma

The Enigma mutation is notable for being the only "normal" mutation that raises your cool.

Location

Enigma is in the Heaven bar within Gangland.

Effects

This mutation grants:

    +2 to cool
    -1 to senses
    immunity to diagnose
    immunity to appraise

Advantages

• You're incognito. Enigma covers up some details on player characters; nobody can see an enigma's @age, and the mutation also hides most description lines added by other mutations when looked at. This mutation is sometimes taken for this cosmetic mystique, especially by new players whose roleplay attempts are frustrated by their Billygoat beards.
• +2 cool. Cool is widely consiered the least useful stat, but it is still a good bonus for Blades users.
• No alcohol restrictions. Alcohol can't be bought while underage in some bars. Alcohol pumps aren't restricted, so nobody really cares about this.

Disadvantages

• Can't be diagnosed. Enigmas need to be confident in understanding their st readouts and knowing the symptoms of various afflictions so that they can seek the correct treatment, because no doctor will be able to diagnose them. Nobody likes a dumbnigma. The doctor in Slagtown's hospital also cannot heal enigmas.
• Can't be analyzed. If enigmas get a mental illness, they're stuck with it unless you run into an Empath, and nobody takes Empath. Fortunately, mentals are rare for everyone but freaks and vampires.
• It's a noob trap. Enigma is good for minmaxers who can make use of the cool and know how to handle the downsides. It's not good for new players who don't understand their debuff messages and whine in corpnet every time they get hit with something they've never seen before. Yes, the cosmetic mystique is cool, but steer clear until you understand the game a little bit.
• Radiation becomes problematic. It's really hard to tell how many rads an enigma has. If you start feeling "sick to your stomach" and taking damage, then run to a medic for a detox pronto. Just like real life, you can and should also regularly fondle me, which will give you a special message if you feel a cancerous lump.
• Makes precise drugging awkward. Most builds that take Enigma won't have tons of Endurance for drugs anyway, but Enigma makes it really hard to measure doses because of the inability to be diagnosed.
• Can't use @buffs. This is another noob-shredder. @buffs is great for experimenting with drugs and figuring out how numbers work. Enigmas can't do that.
• -1 senses. Senses is an easy stat to buff, but -1 senses can still hold back dodge totals and other skills.
• Cool isn't considered a very good stat. Out of all the six stats, it's got the lowest apparent utility (although it does apparently do more things behind the scenes). Enigma's cost is also very high for a mere +2 bonus, especially since cool can be buffed by +4 for cheap with bling.

Appearance

Your appearance when diagnosing or appraising essentially disappears, along with visible mutation effects disappearing from the looking and examining.
